| Windows-specific changes to R |
| ============================= |
| |
| For changes since the release of R 2.0.0 on 4 Oct 2004 see the files |
| CHANGES. |
| |
| |
| rw2000 |
| ====== |
| |
| The miniR distribution no longer included compiled HTML help (to stop |
| it needing 10 floppies rather than 7). |
| |
| Added Rgui script editor by Chris Jackson. Supports object name |
| in window caption in edit() and fix(). |
| |
| Changed preferences menu button "Finish" to "OK". |
| |
| Changed search order for user home directory to use "My Documents" |
| directory after HOME and before HOMEDRIVE/HOMEPATH. |
| |
| Added functions setWindowTitle(), getWindowTitle(), and |
| getIdentification(). |
| |
| Added function getWindowsHandle(). |
| |
| The windows() device has a new 'bg' argument to set the background |
| colour (which still defaults to "transparent"). |
| |
| The C headers files are now installed into R_HOME/include rather than |
| R_HOME/src/include (as on Unix). |
| |
| choose.files() now expands '~' to the user's home directory, as |
| most other file system functions do. |
| |
| (For those building R:) The Makefile now aborts if sub-makes in any of |
| several for-loops fail. |
| |
| R BATCH|SHLIB|INSTALL|REMOVE no longer work: use Rcmd or R CMD (as |
| required under Unix) instead. |
| |
| Rcmd INSTALL now does a `safe installation': it moves away any |
| existing installation of the packages, and moves them back if it |
| fails. In any case, a failed installation is removed. Bundles are |
| processed differently, by combining the DESCRIPTION and DESCRIPTION.in |
| files and processing each package separately. Installation of a |
| bundle now fails as soon as installing any component package fails. |
| It is possible to install the current directory by `Rcmd INSTALL .' . |
| |
| winMenuAdd() and winMenuAddItem() now allow addition of menu items to |
| the console and graphics windows and their popup menus. Repeated |
| addition of the same menu no longer leads to duplicate menus. |
| winMenuDel() now deletes all submenus and items within the menu. |
| |
| Building a complete distribution has an extra step, as the grid |
| vignettes depend on lattice (and so were incomplete in R 1.9.x on both |
| Unix and Windows). |
| |
| The manual way of building packages is now deprecated, and it is no |
| longer possible to use it to build bundles (which was never documented). |
| Cross-building of packages is now done by the XINSTALL script. |
| |
| bringToTop() in MDI mode now brings the whole MDI frame to the top |
| before raising the chosen window within it. |
| |
| There is a new utility to check the installation (not miniR.exe). |
| Open a Command Prompt/MS-DOS window, cd to the top of the installation |
| (where the READMEs are) and run |
| |
| bin\md5check MD5 |
| |
| Any changed or missing files will be reported. You can also |
| double-click to run the file -- it will open a window which will stay |
| open if there are any errors and close quickly otherwise. |
| |
| The `Manuals' menu item in RGui is renamed to `Manuals (in PDF)', and |
| is now greyed out if no manuals are present (which GraphApp was not |
| doing correctly). |
| |
| There is a new component in the main installer for the sources of the |
| help pages (the man subdirectories of the libraries) -- these were |
| not installed under Windows before. |
| |
| The RGui menu item for installing packages from CRAN make uses of the |
| (non-default) setting of install.packages(dependencies = TRUE) to fetch |
| all the other packages needed to run those specified. |
| |
| Improvements to file("clipboard") connections -- see ?file plus some |
| more warnings e.g. if the clipboard becomes full. |
| |
| Memory leaks were fixed in rproxy.dll (used in (D)COM). A break |
| to the debugger during rproxy.dll startup may be triggered by setting |
| the DEBUG_RPROXY environment variable. |
| |
| |
| |
| rw1091 |
| ====== |
| |
| Installing a package with a saved image was not exiting on an error |
| making the image (PR#6769). |
| |
| Installing a package which failed did not return an error code from |
| Rcmd INSTALL (PR#6768). |
| |
| choose.files(multi=FALSE) was liable to give incorrect results (PR#6818). |
| |
| Workaround for bug in Microsoft critical update KB835732: if HOMEPATH |
| environment variable is not set properly, R would not start (PR#6802). |
| |
| Under ESS, Rterm could freeze when quitting (PR#6812). |
| |
| The file.show() internal code failed to close its FindFirst handle and |
| so the directory on which it was used (often the R temporary |
| directory) could not be deleted from within R. |
| |
| If a graphics window is opened in a minimized MDI session, it now |
| uses the physical monitor size instead of the zero-sized MDI frame. |
| |
| Using PgUp whilst recording after a multiple of 4 plots failed to save |
| the current plot. (PR#3663 revisited.) |
| |
| It is now possible to install a package with a man file called (INTRO).Rd. |
| |
| |
| |
| rw1090 |
| ====== |
| |
| Both Rterm and Rgui now give usage information via the --help or -h |
| command-line flag. |
| |
| There is now a "Misc|Break to debugger" menu option, enabled |
| when a debugger is detected (somewhat fallibly), or infallibly by the |
| "--debug" command line option. This will cause a trap to an external |
| debugger, e.g. for running Rgui under gdb. If the menu item is |
| selected when not running under a debugger R is likely to crash. |
| If the "--debug" option is used, R will break to the debugger during |
| command line processing, allowing the startup process to be debugged. |
| |
| Added "stay" argument to bringToTop(), to allow the user to specify |
| that a window should stay on top of other windows. Also added "stay |
| on top" item to the popup menus. All of these require R to be running |
| in SDI mode ("Rgui --sdi" or via the settings in file `Rconsole'). |
| |
| Changed windows() so that new windows fit within the MDI client |
| area. |
| |
| Added winMenuNames() and winMenuItems() functions to query user menus. |
| |
| Added menu items for www.r-project.org and CRAN on the help menu. |
| (Wishlist PR#6492) |
| |
| Added "R" command to be similar to Unix invocation of scripts, e.g. |
| "R CMD INSTALL" is the same as "Rcmd INSTALL". Rcmd still exists for |
| backwards compatibility (and to avoid conflicts over the name `R'). |
| All of R, R CMD and Rcmd now accept --help. |
| |
| Rcmd Rd2dvi can now be specified as such rather than as Rcmd Rd2dvi.sh. |
| |
| Added "Paste commands only" to edit and popup menus in the Rgui console. |
| This allows copying of a block of output, but pasting only the commands |
| back to the console for re-execution. (Code contributed by Tony Plate.) |
| |
| |
| Installation |
| ------------ |
| |
| Parallel make (make -j2, say) can be used, but only usefully on |
| dual-processor (or perhaps hyperthreaded) hosts with at least 384Mb of |
| memory. |
| |
| Installing now sorts in the C locale to ensure that a consistent sort |
| order is used. (Some aspects of sorting used to be done in the locale |
| of the host machine, but Perl and the cygwin-based tools used the |
| ASCII collation order.) |
| |
| The long-untested support for making Windows .hlp files has been withdrawn. |
| |
| There is support for using K. Goto's fast BLAS. On a 2.6Ghz P4 with |
| 1Gb RAM and A a 1000 x 1000 matrix we had the following timings |
| |
| R BLAS ATLAS Goto |
| A %*% A 3.7 0.65 0.56 |
| svd(A) 16.2 7.77 6.83 |
| |
| Note that using a fast BLAS is much less effective for smaller |
| matrices as are more common in statistical applications. |
| |
| Faster assembler code for exponentiation is used. |
| |
| Cross-building of R itself now works again. (It had been broken since |
| 1.8.0.) |
| |
| |
| Building/installing packages |
| ---------------------------- |
| |
| R CMD INSTALL/build/check map path names with spaces in to their short |
| forms. |
| |
| R CMD INSTALL now supports versioned install via --with-package-versions. |
| |
| Installing (binary) package bundles now checks the MD5 sums and |
| reports success, just as for packages. |
| |
| Added "* DONE" to the end of INSTALL logs so --install option to CHECK |
| will work. (This is a repository maintainer option; see |
| src/scripts/check.in for docs). |
| |
| |
| Internal changes |
| ---------------- |
| |
| The fast bmp/png/jpeg code introduced in R 1.8.0 is used even for |
| 256-color displays (as we have now been able to test it on such). |
| |
| Until R 4.2, R's internal malloc etc were remapped to Rm_malloc etc and |
| (only) used in allocating memory for R objects, the Wilcoxon tests and a few |
| other memory-intensive applications. |
| |
| Improved malloc routines from the current version of Doug Lea's malloc |
| (as suggested by David Teller) have enabled large memory areas to be |
| used more effectively, in particular those over 2Gb where OS support |
| were enabled. |
| |
| The initially requested memory is no longer reserved, but as that and |
| today's malloc is able to work with non-contiguous memory chunks that should |
| not matter. |
| |
| The installer uses LZMA compression, so Inno Setup >= 4.1.5 is required. |
| |
| Version 1.2.5 of libpng is now used in binary builds. |
| |
| |
| Bug fixes |
| --------- |
| |
| Fixed list.files() to properly handle paths like "C:", etc. |
| |
| Fixed unlink() to accept empty file list for Unix consistency. |
| |
| Fixed handling of whitespace in Rd2dvi.sh processing of DESCRIPTION |
| files. |
| |
| Fixed handling of "--max-mem-size" syntax error on command line. |
| |
| In RGui, ^T would not transpose the first and second characters on a |
| line. (PR#5593) |
| |
| Fixed junk character at start of a pipe(). (PR#5053) |
| |
| R CMD SHLIB was computing dependencies for all C files, not just those |
| specified on the command line, and building the DLL from all *.o files |
| in the directory. |
| |
| The sizes of metafiles in pixels were often coming out one pixel more |
| than requested, so the background was not quite all painted. Now we |
| over-estimate. |
| |
| Rproxy.dll would cause a crash when transferring large amounts of data. |
| |
| Workaround for Microsoft's esoteric idea that date-times in 1970 before |
| 1970-01-01 00:00:00 GMT are invalid, so as.POSIXct("1970-01-01 |
| 00:00:00") failed in timezones ahead of GMT. |
| |
| Avoid possible segfault with browseURL() on urls of more than 264 chars |
| (although these are not guaranteed to work). |
| |
| |
| |
| rw1081 |
| ====== |
| |
| Files in inst/ are installed later in the process of installing a |
| package (at the request of Ray Brownrigg: the build process was as |
| documented in `Writing R Extensions'). CVS files will not be installed. |
| |
| The fast bmp/png/jpeg code introduced in R 1.8.0 is used for saving |
| from menus (and savePlot()) as well as for the devices. |
| |
| Lines drawn at the extreme top or right of the device region (e.g. by |
| box(which="outer")) might have been drawn one pixel too far from the |
| origin and so perhaps clipped. |
| |
| In 1.8.0 only, the bottom line of pixels was not copied to the file |
| for png/jpeg/bmp device plots (as the Windows GDI function used was |
| incorrectly documented). |
| |
| File src/nmath/dnt.c was not being built for the standalone Rmath library. |
| |
| packageStatus() now works under Windows. |
| |
| Fixed instability under some Windows versions associated with |
| double buffering of the windows() device. (PR#5173) |
| |
| |
| |
| rw1080 |
| ====== |
| |
| The initial size and position of the MDI frame can be set in Rconsole: |
| see the comments in .../etc/Rconsole. The initial position of the |
| console window and graphics windows can be set in Rconsole and in the |
| GUI Preferences editor. |
| |
| The windows() graphics device now has arguments xpos and ypos to set |
| the initial position, overriding the settings in Rconsole. |
| |
| The windows() device has a form of double-buffering: the visible plot |
| is updated only when there has been no plotting for 0.1sec or if the |
| plot has not been updated for 0.5sec. This is optional (but on by |
| default) and the timings can be changed: see ?windows. |
| |
| The bmp/png/jpeg devices are around 10x faster when used on >8-bit |
| displays (but use more memory than before). |
| |
| Rterm reverts to sending warning/error messages to stdout on Windows |
| 95/98/ME. |
| |
| Rcmd BATCH is now handled in C, and works again on Windows 95/98/ME. |
| |
| Rcmd now sets the TEXINPUTS environment variable so that LaTeX |
| macros in share/texmf are available via e.g. "Rcmd latex.exe mydoc". |
| |
| Calling dev.off() (or ending a session) when a windows() device is |
| open and recording plots automatically saves the current plot as the |
| last saved plot. |
| |
| The windows (etc) devices use the Windows character metrics, which at |
| least on some systems have non-zero height and depth for space. This |
| is now overridden. (This showed up in the baseline placing for |
| plotmath expressions containing a space.) |
| |
| A package's DLL used to be built only if standard source files were |
| seen. Now src/Makefile.win is run if present, and if that generates |
| src/$(DLLNAME).dll the DLL is installed. (DLLNAME is the package name |
| unless overridden.) |
| |
| doc/manual/Makefile.win now has targets for fullrefman.{dvi,pdf}. |
| |
| Added "Help | Search help..." menu item to Rgui as a front end to |
| help.search(). |
| |
| |
| |
| Bug fixes |
| --------- |
| |
| The changes to versioned install had ensured that the currently |
| installed copy of a package had its MD5 sums checked, not the version |
| waiting to be installed. Now the correct version is checked. |
| |
| The Copy, Paste, Copy&Paste and Kill buttons in the MDI mode failed to |
| restore focus to the console (see rw1070 RGui changes). |
| |
| The BioConductor people had stolen the menu item for "Install |
| package(s) from CRAN..." so it was not being enabled/disabled |
| properly. |
| |
| The windows() device was not plotting transparent single lines correctly. |
| |
| The scrollbars on the data editor work better for very large matrices, |
| and correctly for more than 65535 columns. |
| |
| The search for a directory for temporary files now checks that TMP and |
| TEMP point to actual writable directories. |
| |
| PKG_FFLAGS is now used if provided. |
| |
| bringToTop() tested against the wrong limit for the device list and so |
| would sometimes not work for high-numbered devices if lower-numbered |
| devices had been closed. |
| |
| getwd() returns paths separated by / not \. |
| |
| rproxy fixed so LAPACK gets loaded properly by (D)COM server. |
| |
| Fixed installer so share/texmf files are installed with developer option. |
| (Sweave.sty continues to be installed in main option.) |
| |
| Fixed MakePkg so that Rd files with missing line ends at EOF are corrected. |
| |
| |
| |
| rw1071 |
| ====== |
| |
| The system() function printed a spurious warning when the input argument |
| was used. |
| |
| The File|Change Dir...|Browse dialog could cause R to crash. |
| |
| Fixed a bug in versioned install of binary package bundles. |
| |
| Help for max.col was not being found in CHTML help: we have worked around |
| a bug in HHW. |
| |
| The maximum allowed `pointsize' for a windows() device has been |
| increased to 48: some people have much bigger screens these days. |
| |
| Rcmd BATCH in rw1070 incorrectly required the R::Utils Perl module. |
| |
| The data editor no longer takes almost all the CPU cycles when running. |
| |
| Fixed a bug in the data editor display that sometimes led to R failing |
| to shutdown. |
| |
| Added some conditional compilation directives to the source so that the |
| replacement malloc() (see INSTALL) need not be used. |
| |
| Changed the installer build code so that patch versions are named |
| rwXXXXpat.exe, development versions are named rwXXXXdev.exe, and |
| beta versions are named rwXXXXbeta.exe. |
| |
| Fixed bugs that caused crash when windows were resized repeatedly.(PR#1711) |
| |
| Changed help to use the 'title' parameter of file.show when displaying |
| help, for consistency with Unix versions. |
| |
| Default in installer changed so a normal user installation will |
| include the source package installation files. |
| |
| Moved the Sweave style file to the main install group. |
| |
| |
| |
| rw1070 |
| ====== |
| |
| This version of R needs more memory and is slower to start up, because |
| it loads more packages by default. This is only likely to be a |
| concern on machines with 16Mb of memory or less than 300MHz |
| processors. For such machines append R_DEFAULT_PACKAGES=ctest to the |
| command line in the shortcut used to run R, when the memory usage will |
| be about equal to that of rw1062. |
| |
| There is a new option to use file("clipboard") to read from or write |
| to the clipboard. As most input/output functions in R use file(), |
| this makes it possible to read data from or write data to the |
| clipboard in many ways, including direct use of read/writeClipboard(). |
| |
| When using download.file() with the internal method and a proxy, the |
| user/password combination can be set to prompt the user with a |
| username/password dialog box, and this will be presented on proxy |
| authentication failure. |
| |
| New function choose.files() for interactive multiple file selection. |
| |
| The output from formatC() uses e+/-0n not e+/-00n for compatibility with |
| other platforms and with format(). |
| |
| A site-wide environment file R_HOME/etc/Renviron.site (or as set by |
| the `R_ENVIRON' environment variable) is now implemented on Windows. |
| |
| The variable .SavedPlots in which plots are stored has been moved from |
| package:base to the user's workspace. |
| |
| The warnings about changing the floating point control word are now |
| optional, selected by options(warn.FPU = TRUE). |
| |
| The main thread is suspended briefly after Rprof() is called. This |
| ensures that the timing thread gets started: on some builds and on |
| single-CPU machines this was not happening in 1.6.x (although it |
| did in 1.5.x, so it must be a compiler/runtime version issue). |
| |
| Installation changes |
| -------------------- |
| |
| The installers have new options under `Additional tasks' which allow |
| the creation of Windows Registry entries to be de-selected by the user. |
| |
| Rcmd.exe and Rprof have been moved to the main distribution (although |
| to use them you will need perl installed). |
| |
| Tcl/Tk 8.4.1 is bundled in rw1070.exe. You can still use your own |
| installation of Tcl/Tk: see the rw-FAQ. |
| |
| The Makefiles that build the installers have been reorganized--see |
| the Maintainers.notes file for details, and INSTALL for new build |
| instructions. |
| |
| HTML help changes |
| ----------------- |
| |
| The format of packages.html has changed, with packages listed by |
| library tree (as happens on Unix) when there is more than one tree. |
| |
| The Java-based search index now covers all packages in all current |
| library trees. |
| |
| When using help.start() with more than one library tree, an attempt is |
| made to correct the URLs in non-standard libraries which point to the |
| R_HOME/doc directory or to the base package. Once this is done a |
| stamp `fixedHTMLlinks' is placed in the package directory, and |
| correction will only be done again if the R installation directory |
| is changed. |
| |
| RGui changes |
| ------------ |
| |
| The `Display file' menu item is now `Display file(s)' and allows |
| multiple file selection. |
| |
| `Install packages from local zip files' from the `Packages' menu can |
| now install several files at once (by selecting multiple files in the |
| file selector). |
| |
| Removed some calls to reset the size of the console, so it will |
| stay maximized throughout window operations. |
| |
| The internal pager will page down with space or CTRL-F and page up |
| with minus or CTRL-B (key sequences which are widely used in Unix |
| pagers). CTRL-A selects all the text. |
| |
| The Change Directory dialog now starts in the current directory, not |
| always at the desktop. |
| |
| RTerm changes |
| ------------- |
| |
| Rterm is now only regarded as interactive if both stdin and stdout are |
| a terminal: this overcomes a problem with getline. |
| |
| System error messages (those which would appear in a dialog box in |
| Rgui) are written on stderr rather than stdout, as are R warnings and |
| error mesages. If you want to capture errors as well as normal output, use |
| something like |
| |
| ...\rterm --vanilla <foo.in >foo.out 2>&1 |
| |
| Installing packages |
| ------------------- |
| |
| Binary packages are retrieved from the bin/windows/contrib/1.7 |
| directory on CRAN, so each new version will have its own set of |
| compatible packages. The zip file names now include the version |
| number, as in mda_0.2-16.zip. |
| |
| Files in the top-level directory of a source package are no longer |
| installed automatically: files to be installed must be put in an `inst' |
| sub-directory (as has long been recommended). (The `demo' and `exec' |
| directories are also installed, as before.) |
| |
| The BLAS library Rblas.dll is no longer automatically linked against |
| when building a package: as on Unix PKG_LIBS=$(BLAS_LIBS) is required |
| in Makevars(.win). |
| |
| MD5 checksums are created on installation from sources (see |
| ?checkMD5sums in package tools), and checked on installation by |
| install.packages(). If you see mismatches, this may be because files |
| are left over from an earlier install of the package: try deleting the |
| whole package directory and re-installing. |
| |
| There is a new command-line flag --auto-zip to Rcmd INSTALL which |
| selects whether to zip up the data and/or help directories depending |
| on their size. This is mainly for use with Rcmd INSTALL --build to |
| install and zip-up packages. |
| |
| |
| |
| rw1062 |
| ====== |
| |
| New functions read/writeClipboard() to read from or write to the clipboard. |
| |
| Hitting the key q (or Q) with an internal pager window in focus will |
| close the pager. |
| |
| Source packages with a DESCRIPTION file with an incomplete last line |
| are now repaired. |
| |
| Rcmd INSTALL tries to find canonical paths to make the check for |
| not installing on top of the source more foolprof. |
| |
| The output when building R or source packages is much quieter. |
| |
| Warnings are printed if a loaded DLL changes the floating point |
| control word: see ?dyn.load for the details. |
| |
| Changed Windows README to README.rw1062, included standard README |
| and RESOURCES file in binary distribution. |
| |
| Printing and copying from the menu of a graphics device now preserve |
| the active graphics device. |
| |
| Fixed a crash that occurred when an attempt was made to view a file in |
| the pager but the file could not be opened (e.g. because another |
| application had it opened with exclusive access). |
| |
| |
| |
| rw1061 |
| ====== |
| |
| Changed titles on help windows so topic name shows when minimized. |
| |
| Dependencies were not being generated properly in packages using C++. |
| |
| share/R/firstlib.R was not being included in the binary distribution. |
| |
| |
| |
| rw1060 |
| ====== |
| |
| The installer program name has changed from SetupR.exe to rw1060.exe. |
| |
| The miniR distribution has grown to eight floppies, and the zip files |
| are no longer distributed on CRAN. |
| |
| The default memory limit has been raised to the smaller of 1Gb and the |
| amount of physical RAM. (See the changes for rw1040 and rw1020 below.) |
| |
| Support for bzip-ed connections has been added to the standard distribution. |
| |
| update.packages() and install.packages() will not try to install a package |
| that is in use (with an informative warning). |
| |
| Using HTML help has changed slightly: in particular |
| help(htmlhelp=TRUE) makes use of the setting of options("browser"). |
| |
| Ctrl-Z in Rgui or Rterm will signal EOF, and so can be used to |
| terminate a read by readLines() or scan(), for example. |
| |
| bmp(), png(), jpeg() and win.metafile() devices can plot multiple |
| pages in separate files. |
| |
| The preferred compiler is gcc-3.1: gcc-2.95.3 can still be used but |
| up-to-date header files are needed. |
| |
| Making packages containing source code automagically makes dependency |
| information for C and C++ code: this is useful when experimenting with |
| packages, and especially for the packages which ship with R. |
| |
| |
| |
| rw1051 |
| ====== |
| |
| file.rename() (which is by default used when saving workspaces) now |
| uses Windows API rather than ISO C functions. This works around a |
| reported problem with Windows thinking a file was in use, and on |
| NT/2000/XP machines makes renaming an atomic operation (rather than |
| delete followed by move). |
| |
| Bulding the standalone Rmath.dll was not making the import library |
| libRmath.a. |
| |
| We may have been able to track down (to the isprint routine) the cause |
| of the FAQ Q2.14 about crashes caused by non-ASCII characters, and |
| hence to circumvent it. |
| |
| File | Print on the menu of a windows() graphics device was not working. |
| |
| The binary distribution could not make packages which needed to link |
| to Rblas.dll. |
| |
| |
| |
| rw1050 |
| ====== |
| |
| There are few new Windows-specific features in this release: it has |
| been tuned to work better with Windows XP and a number of workarounds |
| added. |
| |
| |
| win.print() allows a printer to be specified. |
| |
| help.start(browser=) is now supported: this may be useful if the |
| default browser does not support the Java-based search engine. |
| |
| Very small circles are now forced to be visible: not all Windows |
| versions would display them. |
| |
| Transparency in png() is now supported on `High Color' (16-bit) screens. |
| |
| Changing plot resize type via the menu now works better for the current |
| plot (which is immediately redrawn). |
| |
| BLAS support is now in a separate DLL, Rblas.dll. This means that |
| packages using BLAS (KernSmooth, Matrix, bqtl, fracdiff, gss, |
| odesolve, quadprog, quantreg and subselect amongst those on CRAN) need |
| to be re-built. The advantage is that less space is taken up overall, |
| and ATLAS can be used just by rebuilding Rblas.dll. |
| |
| The installers now use bzip2 compression, so make smaller packages. |
| |
| Cross-building automatically uses STAMP=NO for packages. |
| |
| R and packages can now be built in a directory whose path contains |
| spaces (although we still don't recommend it). |
| |
| If a package contains a script `configure.win' it will be run at the |
| start of installation. |
| |
| Rcmd INSTALL and make pkg-foo test for attempted installation into the |
| source directory. |
| |
| All the configuration options are now in file MkRules. |
| |
| Unzipping is now handled by internal code based on zlib: unzip.dll is |
| no longer required. |
| |
| Launching HTML files from the menus was not working with Netscape 6.2.x, |
| so a workaround has been provided. |
| |
| Rgui.exe.manifest has been added to get XP-style widgets on Windows XP. |
| |
| Some logical colour names have been changed to get consistent colour |
| schemes on Windows XP. |
| |
| The books in the contents of CHTML for packages were not being sorted |
| correctly. |
| |
| The floating-point control setting has been changed to use 64-bit |
| rather than 53-bit mantissas, which will result in slightly |
| different but generally more accurate results. |
| |
| |
| |
| rw1041 |
| ====== |
| |
| Updating HTML indices, e.g. in help.start(), is done within a |
| try() construct. |
| |
| help.start() has a new argument `update'. |
| |
| Making packages now warns if there is a configure script. |
| |
| ga.h was needed for building package `windlgs', but was omitted from the |
| `source package' code for rw1040. It is now included. |
| |
| Rcmd check was failing on Windows 9X, because additions in 1.4.0 were |
| not using Rsystem(). |
| |
| |
| |
| rw1040 |
| ====== |
| |
| If --max-mem-size is given a value greater than 256M, the requested |
| maximum memory is reserved (but not allocated) initially. This will |
| enable the memory to be managed more efficiently, but does increase |
| the chance that R cannot be started. There appears to be an effective |
| limit of about 1700M, at least under Windows 2000. |
| |
| memory.limit() can now increase the memory limit of the current session. |
| This will not work if the limit is currently reached! |
| |
| internet2.dll (see changes for rw1030) must be selected by the |
| --internet2 flag. |
| |
| The miniR* distribution has grown to seven floppies, and no attempt is |
| now made to confine the zip files to floppy-size. |
| |
| The background colour of a windows() window (outside the device |
| region) is now in the `Application Background' colour of the current |
| Windows colour scheme. (It used to be LightGrey.) |
| |
| Gamma correction is now applied to the background colour of a graphics |
| window. (It has long been applied to the foreground colours.) Users |
| of LCD screens may want to set something like gamma=2 when launching a |
| graphics window. |
| |
| savePlot() now supports saving to PDF. |
| |
| There is support for transparency in the devga device (which |
| encompasses screen windows, metafiles, printers and the bmp, jpeg and |
| png devices). The default background colour is "transparent" for all |
| but the bitmap devices: this means that backgrounds are omitted when |
| plotting to/saving to most devices, and the colour that is visible is |
| that of the canvas (see below). The png() device does support |
| transparent backgrounds, but this is not accessible through the menus |
| nor the savePlot() function. |
| |
| The canvas colour of a windows() window can now be specified. This is |
| is gamma-corrected, and defaults to "white". |
| |
| There is a print method for saved plot histories, and individual |
| plots can be replayed from the command line by subsetting a |
| plot history variable. |
| |
| The menus use `...' to indicate that they lead to a dialog box. |
| |
| There is a new menu item `Edit | Data editor...' to edit (via fix()) |
| R objects, especially data frames and matrices. |
| |
| The console pop-up was checking the wrong item for `Buffered output'. |
| |
| Plot histories are saved in a different format: those from earlier |
| versions of R cannot be played back and will be reported as corrupted. |
| |
| Installing a package now first removes the data and demo directories |
| if they exist. |
| |
| Building under (repaired) Cygwin -mno-cygwin environments is no longer |
| supported. You probably do need the compiler system recommended for |
| rw1031 or later. |
| |
| globalvar.h is no longer used: the header files now declare imported |
| variables. This make it essential to use the R header files rather |
| than copying entries from them. |
| |
| A bug in some linkers in linking against ATLAS has been circumvented. |
| There is now a bigger benefit in using ATLAS: on a PII with a |
| 1000x1000 matrix, svd took 288 sec and La.svd 182 sec (without ATLAS) |
| and 59 sec (with); eigen took 163 sec and La.eigen 53 sec (without) |
| and 24 sec (with). |
| |
| |
| |
| rw1031 |
| ====== |
| |
| Lines with lty > 1 and many pieces were being drawn very slowly on |
| Windows 2000 (but not 98/ME). To work around this, such lines are |
| now drawn 5000 pieces at a time. |
| |
| The dialog for the `Change dir' item now uses a standard folder |
| selection widget for its Browse button. |
| |
| White backgrounds are now omitted for metafiles (as they are for |
| postscript, PDF and XFig plots), so white backgounds (the default) |
| appear to be transparent. |
| |
| help.start() now updates the HTML search index (as well as the |
| packages index) when it is started up. link.html.help() works better |
| when R_LIBS omits the drive, and uses relative links for the main |
| library, so R installations can be relocated in the file system. |
| |
| The background colour of the GUI preferences editor and the |
| select.list() popup is now taken from the Windows colour scheme. |
| |
| Rcmd INSTALL now rejects invalid options for --docs (rather than |
| ignoring them), and checks for the R version in the DESCRIPTION file |
| exactly the same way as Rcmd check (so with fewer spurious messages). |
| |
| Added support for building with the ATLAS optimized BLAS library: on a |
| PII this speeds up La.svd on a 500x500 matrix by about 30%, and the |
| multiplication of two 1000x1000 matrices by about 8x. See INSTALL. |
| |
| The recommended compiler system has been changed, but that recommended |
| for rw1030 still works. |
| |
| |
| |
| rw1030 |
| ====== |
| |
| SetupR.exe and miniR* now include the nine `recommended' packages, |
| so the miniR* distribution needs six floppies rather than four. |
| |
| Rgui has a new menu `Packages' with items to load packages, to install |
| packages from CRAN or from local zip files, and to update packages. |
| |
| The packages list shown by help.start() now includes all packages in |
| all libraries, but the search index is still confined to the system |
| library. |
| |
| The installers set up a file association for *.RData files, so |
| double-clicking on a *.RData file launches R in that directory and |
| loads the *.RData file. Also, a *.RData file can be dropped onto a |
| shortcut to Rgui (or Rterm) on the desktop or in Windows Explorer. |
| |
| Drag-and-drop of images (.RData and .rda) and source files (.R) |
| onto the Rgui.exe console window is now supported. |
| |
| Profiling (as described in `Writing R Extensions') is now available. |
| |
| There is a new `Save as PDF' option on the graphics device menu. |
| |
| bringToTop() can specify the console window in Rgui (as -1). |
| |
| The default graphics device is now windows() only in interactive use: |
| otherwise it is postscript(). (This affects the DCOM interface, which |
| is not interactive use.) |
| |
| Support for earlier (pre-Feb 2000) mingw compilers has been dropped: |
| you must use a compiler system that supports --shared and has an |
| in-memory dlltool. |
| |
| Rcmd check has been changed to be more robust to reported problems |
| with Perl's system() command under 16-bit versions of Windows. It now |
| works for us under Windows 98. (It has always worked under NT4 and |
| 2000.) |
| |
| Rcmd SHLIB no longer adds a version tab to the DLL, as this seemed to |
| cause some people problems under Windows 95/98/ME. |
| |
| The correct file version information should now appear on Windows 2000 |
| Version tab under Properties (working around a Windows 2000 bug). |
| |
| rwinst.exe is no longer part of the distribution: use the newer |
| installers to install R, and the Packages menu in Rgui.exe to install |
| pre-compiled packages, or use an external unzip program. |
| |
| The old-style Windows help is no longer part of the standard distribution, |
| but can be made from the sources. It is no longer tested. |
| |
| Make targets such as test-Reg have been moved to directory rw1030\tests. |
| |
| [ DO NOT DO THIS: see ?download.file or rw1040 above: |
| The default internet module modules\internet.dll is built using basic |
| WinSock calls. There is an alternative modules\internet2.dll which uses |
| WinInet calls (and so needs Internet Explorer installed) which can be |
| used as a replacement. (Remove modules\internet.dll and then |
| rename modules\internet2.dll to modules\internet.dll.)] |
| |
| |
| |
| rw1023 |
| ====== |
| |
| Alternative installers based on Inno Setup 2.0.x, either SetupR.exe or |
| miniR* (which fits on four floppies). |
| |
| The location of R_HOME and the version can optionally be recorded in |
| the Registry (and will be used by the DCOM interface). The Inno Setup |
| installers register the installation, and unregister on |
| uninstallation. rwinst.exe has an option to register. Program |
| rw1023\bin\RSetReg.exe will register, and rw1023\bin\RSetReg.exe /U |
| will unregister. |
| |
| The windows() device no longer rounds width and height to the nearest inch. |
| |
| You can override the settings Windows reports for pixels per inch |
| (sometimes it is seriously adrift). See ?windows. |
| |
| File `extract-usage' needed for codoc was missing from rw1022sp.zip. |
| |
| The default memory limit (as reset by --max-mem-size) is set to at |
| least 16Mb, to allow R to start on machines with 8Mb of RAM. |
| |
| link.html.help() has been re-written using connections and so is |
| several times faster. |
| |
| Rcmd INSTALL now allows Windows-style paths to a tar file. |
| |
| rproxy.dll is now built for StatConnector version 0.99: earlier versions |
| are no longer supported. |
| |
| A Windows-specific bug in bitmap() which caused output to appear twice |
| has been fixed. |
| |
| Rcmd check now stops when package-specific tests fail (not just |
| reports on the console). |
| |
| |
| |
| rw1022 |
| ====== |
| |
| The long-running saga of importing R metafiles into Word is over; |
| lines are now visible in screen previews in Word. It was necessary to |
| use `geometric' rather than `cosmetic' pens to achieve scalable line |
| widths in metafiles: Word was failing to show lines drawn with |
| `cosmetic' pens. |
| |
| bringToTop() now works with MDI child windows as well as SDI windows. |
| |
| Rcmd build/check use a different check for a directory, to work around |
| a bug in (some versions of) Windows Perl. |
| |
| The datetime code has been modified to work around a problem reported |
| on a Win98 machine which caused times to be reported in GMT. (This |
| seems a bug in a particular version of msvcrt.dll and few machines |
| were affected.) A side-effect of the changes is that the timezone |
| names reported are usually more sensible (but sometimes less). |
| |
| File etc/Makeconf-tests was missing from rw102Xsp.zip. |
| |
| Rcmd SHLIB now supports compilation from C++ sources. |
| |
| Rterm now saves and resets the console window title. |
| |
| On Win2k, system(intern=TRUE) was failing to reset stderr to the console. |
| |
| |
| |
| rw1021 |
| ====== |
| |
| Pipe connections now work under RGui and embedded R.dll, although |
| slower than under Rterm, and as they run with no stdin or stdout to |
| inherit what you can do with them is limited. They work better for |
| reading than writing. |
| |
| The installer will no longer crash trying to install addons with a |
| long PATH and R_HOME not set. Similarly, Rcmd accepts long paths. |
| |
| Using Rcmd INSTALL with an incorrect path specification ending in \ no |
| longer runs amok. |
| |
| Internal pager no longer fails when given a file of one line and no |
| line ending. |
| |
| Hyperlinks to other packages in CHTML files launched by help() will |
| now work irrespective of the working directory (but like HTML, only |
| to packages in the same library). The .chm files do need to be |
| re-built under this version. |
| |
| help(, winhelp=TRUE) will now find alias topics as well as main items. |
| |
| Hitting the total memory allocation limit set by --max-mem-size will |
| give a warning (and will usually also lead to an error, and that may |
| suppress printing out the warning). |
| |
| There is a new make target test-Reg to run the regression tests (which |
| now do I/0, so might give different results on Windows). |
| |
| Rcmd build with the latest tar.exe will exclude files as intended. |
| |
| There are further improvements in the GUI console receiving output |
| (e.g. from tcltk interactive functions) during input. If you can, |
| arrange to send output in a single piece, or at least a whole line at |
| a time (although partial lines will now work). For example, don't use |
| print() but capture the output in a text connection and use something |
| like cat(paste(outlines, "", collapse="\n)) to output a single string. |
| |
| The initial rescaling is no longer done for windows(rescale="fixed"), |
| and the scrollbars in that mode are more responsive but move the |
| viewport 20 pixels at a time. |
| |
| |
| |
| rw1020 |
| ====== |
| |
| This version has been compiled against msvcrt.dll not crtdll.dll. |
| This gives small speed increases and generally more accurate results. |
| Packages compiled against crtdll.dll will still work (as far as we are |
| aware), but for best results should be re-compiled. (A few packages |
| need to be re-compiled for 1.2.0 on all platforms, and any that used |
| malloc directly need to be recompiled on this one.) |
| |
| |
| This release has a number of changes to bring its behaviour closer to that |
| of Unix versions of R. |
| |
| - The default font for graphics on windows(), win.printer() and |
| win.metafile() devices is now Arial: the font numbers for the |
| Times New Roman and Arial families have been interchanged. |
| |
| - The history is only saved when the workspace is (to be compatible with |
| Unix versions of R) and whether it is restored is controlled by |
| option --no-restore-history (implied by --no-restore and --vanilla): |
| the default remains to restore. |
| |
| - Environment variables R_HISTFILE and R_HISTSIZE can be set to specify |
| the name of the commands history file (default .Rhistory) |
| and its maximum size (in lines, default 512). |
| |
| - More locale support is now enabled where supported by the version of |
| Windows in use. It means that sorting and comparison of character |
| strings will be locale-specific. You may not want this (the sort |
| order in `English_United Kingdom' is aAbB..., for example) and |
| setting Sys.setlocale("LC_COLLATE", "C") should give the previous |
| behaviour. Further, users of Windows 9x/ME should be able to use |
| their native character set for the names of R objects (as NT/2000 |
| users always have: this is caused by the change to msvcrt.dll). |
| (For the benefit of those used to Unix, LC_ALL can be set in the |
| environment, although this is not usually supported by Windows, |
| and setting individual LC_* such as LC_COLLATE will also work.) |
| |
| - It is possible to make DVI and HTML versions of the manuals: |
| see file INSTALL in the source distribution. |
| |
| - New utility Rcmd.exe to emulate R CMD : see below. |
| |
| - unlink() now works the same way on Windows and Unix. Thus on |
| Windows it no longer deletes empty directories, but has a new |
| argument recursive=TRUE to delete directories (empty or not). |
| |
| - The startup code looks for .Renviron, a file pointed to by |
| environment variable R_ENVIRON and then .Renviron in the home |
| directory. This file can contain lines of the forms NAME=value |
| and NAME=${NAME1-value} to take the value of NAME1 if set (and not |
| empty), otherwise `value'. |
| |
| - make check no longer makes R, just runs the tests (as make test |
| always has). Tests are run in the C locale. |
| |
| |
| Gui changes |
| ----------- |
| |
| - There are new console menu items `Load History' on the File menu and |
| `Clear console' on the Edit menu. (The current line is not cleared.) |
| |
| - The menu items `Load/Save Image' are now called `Load/Save Workspace'. |
| |
| - The Print menu item on the File menu of a console or pager now prints |
| the selection if there is one, and the whole (saved) contents otherwise. |
| |
| - There is a new `Save to File' item on the File menu of a console or |
| pager which saves the selection if there is one, and the whole |
| (saved) contents otherwise. |
| |
| - The Rgui console now uses the same history mechanism as Rterm. The |
| history limit is now just on the number of lines (rather than on the |
| number of lines and the total size). The mechanism has been altered |
| so that Rterm records repeated lines (as Rgui always did). |
| |
| - There are some additional command-line editing commands in Rgui: see |
| the Help | Console information screen. (There is also one |
| addition, ^W, in Rterm: see README.rterm.) |
| |
| - Selection works slightly differently: if the selection extends beyond |
| the last character on the line the (invisible) CRLF is made part of |
| the selection, but not if only up to the last character is selected. |
| |
| - The data editor is no longer modal (which seems not to have worked |
| properly in the GraphApp toolkit) and this allows its popups to be |
| modal. |
| |
| - The size of the console scroll buffer can be set in file Rconsole, |
| and resized (upwards) via the GUI preferences editor. |
| |
| - The GUI console copes much better with receiving output (e.g. from |
| tcltk interactive functions) during input. |
| |
| |
| |
| New utilities for preparing packages |
| ------------------------------------ |
| |
| There are several new utilities in the rw1020sp.zip distribution. |
| |
| The utilities Rd2dvi.sh Rd2txt Rdconv Rdindex Sd2Rd are no longer |
| batch files but accessed through a new front-end Rcmd.exe, so if this |
| is in your path (otherwise use ...\rw1020\bin\Rcmd) you can use |
| |
| Rcmd Rd2dvi.sh [options] files |
| Rcmd Rd2txt file |
| Rcmd Rdconv [options] file |
| Rcmd Rdindex [options] files |
| Rcmd Sd2Rd [options] file |
| |
| There are new utilities INSTALL, REMOVE, SHLIB which can be used |
| to install a source package, remove a package and make a DLL, and |
| implementations of the Unix R utilities BATCH, build and |
| check. Invoke these by |
| |
| Rcmd INSTALL [options] pkgdir(s) |
| Rcmd REMOVE [options] pkg(s) |
| Rcmd SHLIB [options] file(s) |
| Rcmd build [options] pkgdir(s) |
| Rcmd check [options] pkgdir(s) |
| Rcmd BATCH [options] infile [outfile] |
| |
| Use option --help with any of these for fuller details. |
| |
| |
| The default for options("papersize") is set according to the locale, |
| and so might be set to "letter" under US or Canadian versions of |
| Windows. |
| |
| Rterm in interactive use sets the title of the window it is running |
| in, and unsets it when it terminates. |
| |
| The Windows memory manager proved to be (far) too slow to work with |
| the new generational garbage collector, so it has been replaced. The |
| current memory manager rarely releases memory back to Windows (but |
| reuses memory very efficiently) so total memory usage will often grow |
| slowly over the course of a session. Memory used for transient large |
| objects will normally be returned at garbage collection. (Once memory |
| usage has gone over the 256Mb of address space that is initially |
| reserved, it is unlikely to be reduced much, but the allocated memory |
| will be reused.) You can compile R to use the Windows memory manager |
| if you need to. |
| |
| New function memory.size() showing the amount of memory currently in |
| use or the maximum that has been used. |
| |
| New command-line option --max-mem-size to set the maximum memory |
| allocation: it has a minimum allowed value of 10M. This is intended |
| to catch attempts to allocate excessive amounts of memory which may |
| cause other processes to run out of resources. The default is the |
| smaller of the amount of physical RAM in the machine and 256Mb. |
| |
| DLLs for packages (including standard packages supplied with R) |
| automatically gain version information when compiled under this |
| version. (Use the Version tab on the Properties dialog box to see it, |
| or the new function DLL.version() within R.) |
| |
| Windows (.hlp) help files now have hyperlinks to other objects within |
| the same package. |
| |
| The windows() graphics device has a new argument `record' to set the |
| initial state of the recording flag, and this defaults to the setting |
| of the option "graphics.record" (and that defaults to FALSE). |
| |
| The windows() graphics device has new options for what happens when it |
| is resized, which can be set from the command line of from the menu. |
| See ?windows for details. |
| |
| New function bringToTop() to bring a graphics window to the top of the |
| windows stack (useful from menu actions, ...). |
| |
| If the options setting for a pager or editor (or the editor argument |
| to edit.default) is a path containing a space, it is automatically |
| quoted if not already quoted. |
| |
| The range of allowed text sizes in a windows/win.print device has been |
| increased, so smaller values of cex will work. (The smallest allowed |
| text size is 2pt not 8pt.) |
| |
| Interactive use of Rterm.exe on Windows 2000 systems is now possible |
| (including under ESS). |
| |
| Better rendering of wide (lwd > 1) and dashed (lty != "solid") lines |
| on the windows/win.print device. |
| |
| The installer rwinst.exe when first asked to install a package tries |
| to find a current installation of R, first from R_HOME if set in the |
| environment, then from the PATH (it looks for ...\rw1020\bin). |
| |
| make pkgcheck-foo will unzip zipped example files if needed. |
| |
| |
| |
| rw1011 |
| ====== |
| |
| New file README.Rterm providing basic documentation on Rterm.exe. |
| |
| undoc() is now available under Windows. |
| |
| There is a new script R_HOME/bin/build.sh, a version of R CMD build. |
| You will need R_HOME set as an environment variable to use it, and you |
| will need the full set of tools from tools.zip (see readme.packages) |
| in your path. |
| |
| The batch wrappers to Perl files Rdconv.bat Rdindex.bat Rd2txt.bat |
| Sd2Rd.bat have been revised to work on more Perl/OS versions. |
| |
| Setting cell widths from the menu in the data editor now works reliably. |
| |
| Having an empty line at the beginning of .Rhistory no longer breaks the |
| history-recall mechanism in Rgui. |
| |
| Characters using the AltGr key now work in interactive use of Rterm. |
| (AltGr used to work like Alt.) |
| |
| Ctrl+V now works as described in a pager (pasting to the console). |
| |
| Other versions of Tcl/Tk may be used by setting TCL_VERSION in |
| MkRules (but only 8.31 and 8.32 have been tested). |
| |
| A file Makevars.win in the src directory of a package will be used in |
| preference to a file Makevars. |
| |
| The Makefiles for packages now allow C++ code (with extension .cc or |
| .cpp or .C) in the src directory. |
| |
| If you use a private library and HTML help, you need to copy R.css |
| from rw1011\library to each private library directory. |
| |
| Function win.version() should give slightly more information (the |
| latest service pack number x.y) on Windows 2000. |
| |
| |
| |
| rw1010 |
| ====== |
| |
| There is now a GUI preferences editor on the Edit menu in Rgui. |
| |
| A data entry editor is now implemented. This is similar to the Unix |
| one (see ?dataentry: that has itself been considerably enhanced in |
| parallel with the Windows version) with the additional features that |
| double-clicking in a cell turns it into an editable field (entered as |
| a new value by navigating away from the cell), and there is a |
| right-click popup menu. |
| |
| Rterm will now load and save the commands history (as Rgui does). |
| There is a new item on the File menu in Rgui to save the commands |
| history at that point in a session, and a new function savehistory() |
| (only applicable in Rgui and Rterm). |
| |
| Colours in Rconsole can be specified as "Windows" and will be taken |
| from the current Windows colour scheme. (The preferences editor will |
| save the actual colour, though.) |
| |
| The placement of multiple pagers is now `random' (so they will not |
| always appear in the exact centre of the screen) and under the MDI |
| interface the pager rows and columns settings are now used. |
| |
| The postscript() device can now spool plots to a printer. You will |
| need a suitable program to send a file to the spooler (or even to send |
| it to ghostscript to interpret PostScript for the printer): the RedMon |
| suite available from http://www.cs.wisc.edu/~ghost/rjl.html and |
| GhostScript distribution sites should provide suitable tools. See |
| ?postscript for further details. |
| |
| The new xfig() device can be used, and a port of xfig to Windows (with |
| an X server and the Cygwin B20.1 environment and X11R6.4 installed) is at |
| ftp.franken.de:/pub/win32/develop/gnuwin32/cygwin/porters/Humblet_Pierre_A/B20 |
| as xfig-3.2.2-cygwin-b20.1-bin.tar.gz. |
| |
| The R DLL and executables now contain standard Windows version |
| information, which will appear on a Version tab of the Properties |
| dialog box in Explorer. |
| |
| The internal unzip and the installer now use unzip5.41, not unzip5.40, and |
| the DLL interface is incompatible. |
| |
| There are changes in the tools needed to build R (see the file INSTALL) |
| and those recommended for building packages from source (see the file |
| readme.packages). |
| |
| New makefile target zipdata-% to zip up data directories in packages. |
| |
| If there is a file `Makefile.win' in a package src directory this |
| will be used rather than MakePkgs (and the tcltk package provides |
| an example). |
| |
| There is an example package `windlgs' in the package sources |
| distribution that shows how to use graphapp to build dialog boxes to |
| be called from menus, with a worked example of a t test done in three |
| ways. More details of graphapp, including a tutorial and a reference |
| manual, are at http://www.cs.usyd.edu.au/~loki/graphapp. |
| |
| Optional support for the Tcl/Tk interface. To use this you need to |
| install tcl831.exe from dev.scriptics.com, and you will need the Tcl |
| and Tk dlls in your path. Also, you need to set the environment |
| variable TCL_LIBRARY, to something like c:/Program Files/Tcl/lib/tcl8.3. |
| The demos(tk*) will work on Windows. |
| |
| The R mathematical functions can now be built as a DLL for use |
| with your own C programs. See src/nmath/standalone/README in the |
| sources. |
| |
| Rdconv.bat no longer depends on having a Unix-compatible `cat' program |
| in your path. |
| |
| A long-standing bug in the (vertical) alignment of symbols in plotmath |
| has been corrected. |
| |
| Pagers should no longer flash when launched. |
| |
| Launching a pager or data editor or graphics window now brings it |
| to the front, even from Rterm.exe. (Not for Tcl/Tk windows, unfortunately.) |
| |
| Failure to load a DLL with dyn.load now gives extended error information. |
| |
| |
| |
| rw1001 |
| ====== |
| |
| The installer, rwinst.exe, now checks for ZIP files as well as zip files, |
| as some browsers manage to map filenames to uppercase. |
| |
| There are batch files Rd2txt.bat Rdconv.bat Rdindex.bat Sd2Rd.bat |
| which are the equivalent of the Unix `R CMD foo' utilities mentioned in |
| `Writing R Extensions'. To use these you must have R_HOME set as an |
| environment variable (using the form P:/R/rw1001). There is also a |
| shell script Rd2dvi.sh which you can use if you have sh.exe (as |
| used to compile packages) and latex etc. The environment variable |
| XDVI sets the previewer, defaulting to xdvi.bat. |
| |
| A file `Makevars' in the `src' directory of a package can be used to |
| add to/override the MakeDll makefile used to make foo.dll, as on Unix. |
| (See `Creating shared libraries', section 3.4 of `Writing R Extensions'.) |
| |
| Under rare conditions (lots of very short input lines) the history buffer |
| could overrun and so cause crashes. This has been possible since rw0623, |
| but first caused reported problems in rw1000 and has now been fixed. |
| |
| Certain HP printer drivers (e.g. the 6/6MP-Postscript driver) reset the |
| FPU and so were causing crashes. This has been circumvented in this |
| version by restoring the settings before and after each page. |
| |
| Building on a non-default drive should be more reliable, as Perl is |
| used to find the current drive. |
