| \itemize{ |
| \item Windows-specific changes will now be announced in the |
| common NEWS file. |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.15.0}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item The 32-bit and 64-bit builds are now treated equally, as it |
| is anticipated that 64-bit R will soon be (if not already) the |
| more commonly used. This entails: |
| |
| The \command{Rterm} or \command{Rgui} title mentions 32-bit as |
| well as 64-bit. |
| |
| The desktop icons are labelled \code{R i386} and \code{R x64}. |
| |
| \command{R CMD INSTALL} for a package with compiled code will fail |
| if compilation fails for any of the installed sub-architectures: |
| use \option{--no-multiarch} to override this. |
| |
| \item \code{postscript(file = "|cmd")} now works on Windows. |
| |
| \item \code{file.symlink()} is now implemented on NTFS file |
| systems on Vista or later, for accounts which have suitable |
| permissions (and most will not). It can link existing |
| directories, and existing-or-not files. |
| |
| \item There is a new function \code{Sys.junction()} to create |
| junction points on NTFS file systems. |
| |
| \item C-level error formats now use the trio library, and so for |
| example output \samp{1.53e-11} (as required by C99) rather than |
| \samp{1.53e-011}. |
| } |
| } |
| |
| \subsection{INSTALLER}{ |
| \itemize{ |
| \item The installer has many fewer options with more files always |
| being installed, as a few Mb of file space is nowadays no longer |
| an issue. |
| |
| \item It is now possible to select \sQuote{64-bit Files} |
| from the standard installer even on a 32-bit version of Windows. |
| } |
| } |
| |
| \subsection{PACKAGE INSTALLATION}{ |
| \itemize{ |
| \item As the current toolchain uses only 32-bit executables, it is |
| possible to compile a package for both architectures on 32-bit |
| Windows provided both architectures of \R have been installed: use |
| \command{Rcmd INSTALL --compile-both}. |
| |
| \item \code{Rcmd INSTALL --merge-multiarch} will work (but do a |
| normal install) if only one architecture is installed. |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Due to a race condition, some graphics changes were not |
| flushed to the display if another graphics window was closed at |
| nearly the same time. (Reported by Michael Sumner.) |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.14.2}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item \code{bitmap()} and \code{dev2bitmap()} look for |
| \command{gswin64c.exe} (as used by 64-bit GhostScript), in |
| preference to \command{gswin32c.exe}. |
| } |
| } |
| |
| \subsection{INSTALLATION}{ |
| \itemize{ |
| \item The sources (and packages) can now be compiled using the |
| multilib toolchain developed for \R 2.15.x: see the |
| \samp{MULTI} macro in \file{MkRules.dist}. This toolchain is used |
| for the CRAN binary distribution. |
| } |
| } |
| |
| \subsection{PACKAGE INSTALLATION}{ |
| \itemize{ |
| \item The preferred toolchain has changed since the one used for |
| \R 2.12.0 to 2.14.1: see the\sQuote{R Installation and |
| Administration manual}. Compiled code (except DLLs) may be |
| incompatible with previous toolchains (and compiled C++ code |
| almost certainly will be: users of \CRANpkg{Rcpp} take care). |
| |
| Ensure that the settings in \file{MkRules.local} are appropriate |
| to the toolchain you use. |
| |
| \item There is a new macro (aka make variable) |
| \samp{SHLIB_PTHREAD_FLAGS}. This is set to \option{-pthread} on |
| builds using toolchains which support it, and should be included |
| in both \samp{PKG_CPPFLAGS} (or the Fortran or F9x equivalents) |
| and \samp{PKG_LIBS}. |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Using a prompt of more than 80 characters in |
| \code{readline()} could cause a buffer overflow in Rterm. |
| (Reported by Henrik Bengtsson.) |
| |
| \item Some of the custom messages in the installer were corrupted: |
| add a BOM mark to the file as now required by Unicode Inno Setup. |
| (\PR{14816}) |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.14.1}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item The \code{Save as} menu item on the script |
| editor adds extension \file{.R} to a file name without an extension. |
| |
| \item In package \pkg{parallel}, \code{detectCores(logical = |
| FALSE)} makes an OS-dependent attempt to find the number of |
| physical cores. It usually succeeds, even on XP. |
| } |
| } |
| |
| \subsection{PACKAGE INSTALLATION}{ |
| \itemize{ |
| \item The directory pointed to by \env{USER_LOCAL} can now have |
| architecture-specific sub-directories \file{lib/i386} and |
| \file{lib/x64}. |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item The fix for \PR{14543} caused stack problems with outputting |
| large \R objects (e.g., data frames of 25,000 items). (\PR{14698}) |
| |
| \item In a double-byte locale (Chinese, Japanese, Korean), |
| \code{grep()} and friends might have used byte-wise matching of |
| strings in the native encoding. (\PR{14622}) |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.14.0}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item The \code{yLineBias} of the \code{windows()} family of |
| devices has been changed from 0.1 to 0.2: this changes slightly |
| the vertical positioning of text (including axis annotations). |
| This can be overridden by setting the new \code{"ylbias"} graphical |
| parameter. This was done for consistency with other devices |
| such as \code{pdf()}. |
| |
| \item \command{R CMD build} once again attempts to preserve file |
| permissions on Windows. |
| |
| \item There is support for cairographics-based devices using the |
| same code as on Unix-alikes. This can be selected by the new |
| \code{type} argument of the bitmap devices \code{bmp()}, |
| \code{jpeg()}, \code{png()} and \code{tiff()}, and devices |
| \code{svg()}, \code{cairo_pdf()} and \code{cairo_ps()} are now |
| available on Windows. |
| |
| These are not compiled in by default when building from source: |
| see the instructions in the \sQuote{R Installation and |
| Administration Manual}. |
| |
| \item All the Windows-specific graphics devices now have a |
| \code{family} argument. If non-empty this specifies an initial |
| family to be used for fonts 1--4. If empty the fonts specified in |
| the \file{Rdevga} configuration file are used for the Windows GDI |
| devices and \code{"sans"} for cairographics-based devices. |
| |
| This will generally be a Windows font name such as |
| \code{"Lucida Bright"} or one of the device-independent names |
| (\code{"sans"}, \code{"serif"} and \code{"mono"}). Outside |
| Western Europe you may need to select a family that better |
| supports your locale such as \code{"Arial MS Unicode"} or one |
| specific to Chinese/Korean/Thai \dots{}. |
| |
| \item There is a new \file{antialias} argument to |
| \code{windows()}, \code{win.print()} and the bitmap devices. |
| This is an option that can be set in \code{windows.options()} to |
| set the default for \code{windows()} (and \code{win.graph()}). |
| |
| This gives a hint to the Windows plotting system. Whether |
| anti-aliasing is actually used principally depends on the OS |
| settings: this argument should at least be able to turn it |
| off. The default behaviour (unchanged from before) is that Windows |
| will use anti-aliasing for screen devices (and bitmap devices, as |
| they plot on a hidden screen) if ClearType has been enabled. For |
| those not using ClearType, \code{windows.options(antialias = |
| "cleartype")} will make this the default, and it will probably |
| give more legible plots. |
| |
| The argument can also be used for the cairographics-based versions |
| of the bitmap devices. |
| |
| \item The \sQuote{Update packages ...} menu item now runs |
| \code{update.packages(ask="graphics", checkBuilt=TRUE)}. |
| |
| \item \code{R CMD INSTALL} preserves the package-directory |
| modification time when it restores an earlier install of the package. |
| |
| \item File extensions \code{.xz}, \code{.rda} and \code{.RData} |
| have been added to those which default to binary transfer for |
| \code{download.file()}. |
| |
| \item \code{install.packages()} and \command{R CMD check} have a |
| small delay after removing a directory to counteract some |
| interference from anti-virus software. |
| |
| \item There is a Danish translation of the RGui menus. |
| } |
| } |
| |
| \subsection{INSTALLATION}{ |
| \itemize{ |
| \item Compilation of C and Fortran code now uses the optimization |
| flag \option{-mtune=core2}: this will improve performance a few |
| percent on recent CPUs at the expense of those which are several |
| years old. Its effect is particularly evident on 64-bit builds. |
| |
| This can be overridden when building from the sources: see the |
| \samp{EOPTS} macro defined in file \file{MkRules.dist}. |
| |
| \item Where both 32- and 64-bit versions of R are installed, the |
| file association for \file{.RData} files defaults to 64-bit R (it |
| defaulted to 32-bit in R 2.12.x and 2.13.x). |
| |
| \item There is preliminary support for \sQuote{multilib} |
| toolchains which use options \option{--m32} or \option{--m64} to |
| select the architecture; set the appropriate macros in |
| \file{MkRules.local}. |
| |
| It is the intention to move to such a toolchain when they become |
| mature enough. |
| } |
| } |
| |
| \subsection{PACKAGE INSTALLATION}{ |
| \itemize{ |
| \item \file{Rzlib.dll} (sometimes used in packages \emph{via} |
| \samp{$(ZLIB_LIBS)}) does not include the buggy gzio % for balance: $ |
| interface from zlib 1.2.5. |
| } |
| } |
| |
| \subsection{DEFUNCT}{ |
| \itemize{ |
| \item{zip.unpack()} (deprecated in \R 2.13.0) is defunct: |
| use \code{unzip()} instead. |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Raster drawing on \code{win.metafile()} (or copying a plot |
| that includes a raster image from another device to a Metafile) |
| now does not crash. (Reported by Stefan Gelissen.) |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.13.2}{ |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item The fix for \PR{14583} caused inconsistent behaviour in other |
| areas, e.g.\sspace{}\PR{14628}, extra lines appearing in image displays, |
| and uneven bases on histograms. (\PR{14632}). |
| |
| \item Opening large numbers of \code{windows()} graphics devices |
| could cause some of them to fail to redraw (\PR{14668}). |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.13.1}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item \command{R CMD build} no longer attempts to preserve file |
| permissions on Windows, because Windows (unlike POSIX-compliant |
| OSes) stops read-only files being deleted in version-control |
| directories. |
| |
| \item \code{shell.exec()} now interprets files relative to the current |
| working directory (rather than \samp{R_HOME}). |
| |
| \item \code{file.info()} now accepts \sQuote{file} names with |
| trailing directory separators, even though such names are invalid |
| on Windows. |
| |
| \item The \code{windows()} family of devices now supports() |
| per-pixel alpha for raster images. |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Launching the PDF manuals from the Rgui menus did not work |
| on some versions of Windows. |
| |
| \item The windows() screen device would sometimes fail to plot |
| (visibly) points with \code{pch="."}. \PR{14583} |
| |
| \item \code{system()} and related functions sometimes failed |
| when run in \file{Rgui}. |
| |
| \item Saving to PDF from the menu of a \code{windows()} device |
| used defaults for \code{family}, \code{fg} and \code{bg} from |
| \code{ps.options()} rather than \code{pdf.options()} (but |
| the factory-fresh defaults were the same). |
| |
| \item Shutting down the \R session cleaned up the temporary |
| directory before closing all graphics devices. On Windows this |
| necessitated changing the working directory, so some devices |
| (e.g., \code{tiff()}) could write files in the wrong directory if |
| closed during shutdown. The order has been reversed. |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.13.0}{ |
| \subsection{WINDOWS VERSION}{ |
| \itemize{ |
| \item Windows 2000 is no longer supported. (It went end-of-life in |
| July 2010.) |
| } |
| } |
| |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item \code{win_iconv} has been updated: this version has a change |
| in the behaviour with BOMs on UTF-16 and UTF-32 files -- it |
| removes BOMs when reading and adds them when writing. (This is |
| consistent with Microsoft applications, but Unix versions of |
| \code{iconv} usually ignore them.) |
| |
| \item Support for repository type \samp{win64.binary} (used for |
| 64-bit Windows binaries for \R 2.11.x only) has been removed. |
| |
| \item The installers no longer put an \sQuote{Uninstall} item on |
| the start menu (to conform to current Microsoft UI guidelines). |
| |
| \item Running \R always sets the environment variable \env{R_ARCH} |
| (as it does on a Unix-alike from the shell-script front-end). |
| |
| \item The defaults for \code{options("browser")} and |
| \code{options("pdfviewer")} are now set from environment variables |
| \env{R_BROWSER} and \env{R_PDFVIEWER} respectively (as on a |
| Unix-alike). A value of \code{"false"} suppresses display (even |
| if there is no \command{false.exe} present on the path). |
| |
| \item If \code{options("install.lock")} is set to \code{TRUE}, |
| binary package installs are protected against failure similar to |
| the way source package installs are protected. |
| |
| \item \code{file.exists()} and \code{unlink()} have more support |
| for files > 2GB. |
| |
| \item The versions of \command{R.exe} in |
| \file{R_HOME/bin/{i386,x64}/bin} now support options such as |
| \command{R --vanilla CMD}: there is no comparable interface for |
| \file{Rcmd.exe}. |
| |
| \item A few more file operations will now work with >2GB files. |
| |
| \item The environment variable \env{R_HOME} in an \R session now |
| uses slash as the path separator (as it always has when set by |
| \command{Rcmd.exe}). |
| |
| \item \command{Rgui} has a new menu item for the PDF |
| \sQuote{Sweave User Manual}. |
| } |
| } |
| |
| \subsection{DEPRECATED}{ |
| \itemize{ |
| \item{zip.unpack()} is deprecated: use \code{unzip()}. |
| } |
| } |
| \subsection{INSTALLATION}{ |
| \itemize{ |
| \item There is support for \samp{libjpeg-turbo} \emph{via} |
| setting \code{JPEGDIR} to that value in \file{MkRules.local}. |
| |
| Support for \samp{jpeg-6b} has been removed. |
| |
| \item The sources now work with \samp{libpng-1.5.1}, |
| \samp{jpegsrc.v8c} (which are used in the CRAN builds) and |
| \samp{tiff-4.0.0beta6} (CRAN builds use 3.9.1). It is possible |
| that they no longer work with older versions than |
| \samp{libpng-1.4.5}. |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Workaround for the incorrect values given by Windows' |
| \code{casinh} function on the branch cuts. |
| |
| \item Bug fixes for drawing raster objects on \code{windows()}. The |
| symptom was the occasional raster image not being drawn, especially |
| when drawing multiple raster images in a single expression. |
| Thanks to Michael Sumner for report and testing. |
| |
| \item Printing extremely long string values could overflow the |
| stack and cause the GUI to crash. (\PR{14543}) |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.12.2}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item Building badly-written vignettes which used the default |
| device (\code{pdf(file = "Rplots.pdf")}) could leave the device |
| open and hence the file \file{Rplots.pdf} could not be removed on |
| Windows: all devices are now closed. |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item In some circumstances the caret (cursor) could be positioned |
| incorrectly. (\PR{14460}) |
| |
| \item When loading \file{Rconsole} from disk, a spurious warning |
| message was sometimes shown. |
| |
| \item In \R 2.12.1, \code{system()} sometimes passed an empty |
| input stream to the new process rather than allowing user input. |
| |
| \item The internal method for \code{untar()} does a better job of |
| unravelling symbolic links in the tarball (but still with many |
| limitations). |
| |
| \item The graphical dialog version of \code{select.list()} could |
| cause later dialogs to fail if Windows events were not processed |
| between the calls. |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.12.1}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item \code{system()} and \code{system2()} with output redirected |
| to a character vector now give a warning if the command returns a |
| non-zero error code. (This is what a Unix-alike does as from \R |
| 2.12.0.) |
| |
| \item \code{system()} and \code{system2()} no longer discard |
| output from the command to stdout and stderr as often as they used |
| to, and more cases of \code{system2()} are implemented. |
| |
| \item \code{stdout} is now flushed after echoing the input line. |
| |
| \item The internal implementation of \code{tar()} (package |
| \pkg{utils}) is now supported on Windows. |
| } |
| } |
| |
| \subsection{INSTALLATION}{ |
| \itemize{ |
| \item The MSI installer is now made by an \R script, and there is |
| now support for 64-bit builds. (Unlike the Inno Setup installer, |
| there are separate MSI installers for 32- and 64-bit Windows.) |
| |
| It is now built using \command{WiX 3.x} rather than \command{WiX |
| 2.0}. (As a result it is about 25\% smaller.) |
| } |
| } |
| |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Some warning/error messages from \code{dyn.load()} could be |
| masked in \command{Rgui} on Windows 7, as that OS can return |
| messages containing carriage returns and \command{Rgui} does not |
| support overwriting. |
| |
| \item Filenames could not be specified using backslashes in |
| \code{Sweave()}. |
| |
| \item In \R 2.12.0, \code{system(intern = TRUE)} captured |
| \file{stderr} on \command{Rterm} when it was documented to only do |
| so on \command{Rgui}. |
| |
| \item \command{Rgui} in \R 2.12.0 (only) did not always handle lines |
| containing carriage returns (\samp{\r}) correctly: sometimes |
| random characters where shown. |
| |
| Since carriage returns have been supported in \command{Rgui}, |
| the cursor positioning after outputting a line containing a |
| carriage return had been unreliable. |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.12.0}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item A sub-architecture is used for 32-bit (i386) as well as |
| 64-bit (x64) builds. 32-bit packages containing compiled code |
| need to re-installed for this release (64-bit packages built |
| for 2.11.x will most likely still work). |
| |
| Architecture-specific files (such as \file{Rgui.exe} and |
| \file{Rscript.exe}) are now in \file{R_HOME/bin/i386} or |
| \file{R_HOME/bin/x64}. |
| |
| Because many people expect it, there is an executable |
| \file{R_HOME/bin/R.exe}, which accepts \option{--arch} and |
| launches either \file{R_HOME/bin/i386/R.exe} or |
| \file{R_HOME/bin/x64/R.exe}, and analogously for |
| \file{Rscript.exe}. If not specified by their argument |
| \option{--arch}, these check the environment variable |
| \env{R_ARCH} for the architecture to use. |
| |
| \item The \command{Rgui} console now has an optional blinking |
| caret (cursor) to assist screen readers for the visually |
| impaired. |
| |
| \item \code{normalizePath()} now signals a warning instead of an |
| error when the input path does not exist. It attempts partial |
| normalization, or if that fails, returns the original input. |
| |
| \item All the \command{Rcmd} sub-commands except \code{config} and |
| \code{Sd2d} are now handled internally rather by shell scripts. |
| |
| \item \command{Rcmd} has a new sub-command \command{texify} to run |
| MiKTeX's \file{texify.exe} with arguments to find files such as |
| \file{Sweave.sty}. See the examples in \code{?Sweave}. |
| |
| \item \code{system(intern = FALSE)} now returns \code{127} (the |
| same as Unix-alikes) rather than \code{-1} if the command cannot |
| be run, and (like Unix-alikes) no longer gives a warning. |
| |
| \item \command{Rscript -e} and similar use a temporary file, and |
| now work harder to ensure that filename is not the same as some |
| other simultaneous \R process. |
| } |
| } |
| \subsection{INSTALLATION}{ |
| \itemize{ |
| \item The preferred toolchain for 32-bit builds (including |
| packages) is now based on \command{gcc 4.5.0}: see the \sQuote{R |
| Installation and Administration Manual}. |
| |
| \item It is now possible to build \R and the standard installer |
| without Perl: only maintainer-mode tasks now need Perl. |
| } |
| } |
| \subsection{64-bit NEWS}{ |
| \itemize{ |
| \item The 32- and 64-bit distributions have been merged: |
| |
| There is a combined installer (called |
| \file{R-<version>-win.exe}). When used under 32-bit Windows |
| this works as before and installs 32-bit \R. When used under |
| 64-bit Windows there are options to install either or both of |
| 32- and 64-bit \R: the default is to install both. |
| |
| The default package type is \code{"win.binary"} on both 32- and |
| 64-bit builds: a single repository contains binary packages for |
| both architectures. This is in place for CRAN, CRAN extras and |
| BioC: \code{type = "win64.binary"} can still be used for any |
| repositories which follow the \R 2.11.x convention. With the |
| default filters (see \code{?available.packages}) packages will |
| only be offered if they are available for the current |
| architecture. |
| |
| The default personal library, e.g.\sspace{}\file{~/R/win-library/2.12} |
| is now the same for both 32- and 64-bit \R. |
| |
| \item The recommended 64-bit toolchain has been changed to one |
| that does not add leading underscores. See |
| \url{http://cran.r-project.org/bin/windows/Rtools/}. Any static or import |
| libraries for external software used in installing packages will |
| need to be re-compiled for this toolchain, but the use of DLLs is |
| unaffected. |
| |
| \item For those building \R from the sources, the 64-bit |
| \code{Tcl} binary distribution for 2.12.x is in file |
| \file{R64a_Tcl_8-5-8.zip} and contains e.g.\sspace{}directory |
| \file{Tcl/bin64} and not \file{Tcl/bin}. |
| } |
| } |
| \subsection{PACKAGE INSTALLATION}{ |
| \itemize{ |
| \item The deprecated environment variable \env{RHOME} is no longer |
| set when a package is installed: use \env{R_HOME} instead (and |
| depend on \code{R (>= 2.9)} ). |
| |
| \item Package installation, including \file{configure.win} |
| scripts, can use \code{$\{R_HOME\}/bin$\{R_ARCH_BIN\}} as a |
| portable way to find the binaries such as \file{Rscript.exe}. |
| } |
| } |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item \command{R.exe} when used in place of \command{Rterm.exe} |
| set the environment variables set by \command{R CMD}. Conversely, |
| \command{R CMD BATCH} did not. |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.11.1 patched}{ |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item \code{file.rename()} now waits for the rename to complete |
| before returning, so that operations on the new filename will |
| not fail. |
| |
| \item \code{Sys.info()} and \code{win.version()} now report |
| Windows 7 as such (and not as Vista), and \code{Sys.info()} now |
| reports the machine type as \code{"x86-64"} on 64-bit platforms. |
| |
| \item \code{serialize()} to a raw vector works around the dismal |
| performance of Windows' memory manager by allocating much larger |
| chunks of memory less frequently. |
| |
| \item \code{readClipboard()} could cause a segfault with certain |
| clipboard data. |
| |
| \item A fix intended for Mac OS X was incorrectly applied to |
| Windows, so \code{iconv(x, from, "")} in a C locale was |
| interpreted as requesting translation to UTF-8. |
| |
| \item \code{system(intern=TRUE)} often returned \code{0} |
| rather than an error status if the command could not be found, if |
| run from \code{Rterm} or from \code{Rgui} with |
| \code{show.output.on.console = FALSE}. |
| |
| \item \code{memory.limit()} did not allow sizes greater than |
| 4095 on 64 bit builds. (\PR{14372}) |

| \section{CHANGES IN R VERSION 2.11.1}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item The \command{Rgui} console, pagers and editor on the 64-bit |
| build now have a title bar icon. |
| |
| \item The outer frame/console for \command{Rgui/Rterm} mentions |
| '(64-bit)' to make it easier to distinguish running copies of \R. |
| |
| \item The package entries in listbox shown by the \code{Install |
| package(s) ...} menu are now explicitly sorted in the current |
| locale (as they were in most previous releases, but not in |
| 2.11.0). |
| |
| \item \command{R CMD INSTALL} can install zipfiles as binary |
| packages. |
| |
| \item Errors in the \file{Rconsole} file are ignored: silently on |
| startup, with a warning when \file{Rconsole} is loaded |
| interactively. |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.11.0}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item There is now a native x64 Windows port, with a binary installer |
| and binaries of packages available on CRAN. See the 'R |
| Administration and Installation Manual' and the 'R for Windows FAQ'. |
| |
| \item \command{Rcmd cmd} (or \command{R CMD cmd}) now runs an |
| arbitrary '\option{cmd}' if '\option{cmd}' is not one of the |
| builtin commands, and does not have extension '\file{.sh}' or |
| '\file{.pl}' (when it is run as a shell or Perl script |
| respectively). This is done by passing '\option{cmd}' to the |
| command interpreter determined by the \env{COMSPEC} environment |
| variable (which in a vanilla Windows system points to |
| \file{cmd.exe}). |
| |
| \item \code{X11()} and \code{x11()} gain additional arguments to |
| be more similar to the Unix \code{X11()} device. |
| |
| \item \code{file.rename()} can work across volumes (by copy-and-delete). |
| |
| \item The main HTML help page now links to this \file{CHANGES} file. |
| (Suggested by Henrik Bengtsson.) |
| |
| \item \code{strftime(format = "\%z")} now gives the timezone names |
| used by the Olson database and not those used by Windows. |
| |
| \item \code{iconv(to = "ASCII")} no longer transliterates, but |
| \code{iconv(to = "ASCII//TRANSLIT")} will. This makes |
| \code{tools::showNonASCII()} work the same way as on other platforms. |
| |
| \item \code{readRegistry()} can look at either the 32- or 64-bit view |
| of the Registry on 64-bit Windows. |
| } |
| } |
| \subsection{INSTALLATION}{ |
| \itemize{ |
| \item The \code{Tcl} timezone files (3Mb on disc) are now an |
| optional part of the installation: they would be very rarely used |
| with \R. |
| |
| \item \file{RSetReg.exe} has been updated to (un)set the |
| version-specific keys in the same way as the main installer, and |
| to have the optional argument \option{/Personal} to (un)set the |
| per-user rather than the per-machine keys (which need |
| administrative access). |
| |
| \item When building \R, the recommended way is now to supply a file |
| \file{R_HOME/src/gnuwin32/MkRules.local} instead of editing |
| \file{MkRules}: there is now no \file{MkRules} file in the |
| distribution, but one is generated during the build process. |
| |
| \file{MkRules.local} can be generated by copying and editing |
| \file{MkRules.dist}. |
| |
| \item The MSI installer defaults to an all-user (per machine) |
| install (by setting the \code{ALLUSERS} property to \code{1}). |
| This can be changed at installation, and it can be built for a |
| user-mode install (see \file{MkRules.dist}). |
| } |
| } |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Using \code{ESC} to interrupt a \code{system()} call could |
| cause \R to become unstable. |
| |
| \item \code{0^1i} (which should be complex \code{NAN}) was |
| incorrect. |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.10.1 patched}{ |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item Some of the MDI toolbar buttons (e.g., \code{"Open Script"}) |
| did not return the focus to the console if the user cancelled the |
| action. |
| |
| \item \code{system()} (and hence \code{shell()}) did not always |
| set the standard file handles properly, so some programs would |
| not run. |
| |
| \item \code{setWinProgressBar()} did not check the type of its |
| \code{'title'} and \code{'label'} arguments and might have |
| crashed if they were mis-specified. It now does, thanks to a |
| report by Greg Snow. |
| } |
| } |
| } |
| \section{CHANGES IN R VERSION 2.10.1}{ |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item The installer did not properly record help type choices in |
| \file{R_HOME/etc/Rprofile.site}. |
| |
| \item \command{Rcmd INSTALL} once again uses |
| \option{--no-restore}, for consistency with the Unix version and |
| \R 2.9.2. |
| |
| \item The HTML package index was not constructed properly when the |
| library path was specified with backslashes. (Patch submitted |
| by Gabor Grothendieck.) |
| } |
| } |
| } |
| |
| \section{CHANGES IN R VERSION 2.10.0}{ |
| \subsection{NEW FEATURES}{ |
| \itemize{ |
| \item \code{windows()} now has a parameter \code{fillOddEven} |
| (default \code{TRUE}), which controls the mode used for polygon |
| fills of self-intersecting shapes. |
| |
| \item The functions \code{arrangeWindows()} and |
| \code{getWindowsHandles()} have been added to give more |
| programmatic control to the appearance of windows in an R |
| session. |
| |
| \item A \sQuote{Windows} menu has been added to the SDI version of |
| the \R GUI, and the corresponding menu in the MDI version has |
| been expanded slightly. |
| |
| \item The \code{libpng} library has been updated to version 1.2.40. |
| |
| \item The remaining Perl scripts \code{build}, \code{check}, |
| \code{Rprof}, \code{Sd2Rd} in \file{R_HOME/bin} now have extension |
| \file{.pl}. |
| |
| \item \code{Rcmd} (or \code{R CMD}) can now run \file{.sh} (shell) |
| and \file{.pl} (Perl) scripts anywhere on the path (as well as |
| \file{.bat} and \file{.exe} files as before). |
| } |
| } |
| \subsection{PACKAGE INSTALLATION}{ |
| \itemize{ |
| \item \command{Rcmd SHLIB} (which is used by \command{Rcmd |
| INSTALL}) now calls \code{make} without a target, rather than |
| target \code{'all'}. This is now the same as on Unix, and was |
| announced in the \file{NEWS} file for 2.9.0. |
| |
| \item Help files are no longer zipped: rendering as text, HTML, |
| latex or examples is now done when needed. |
| |
| Options \option{--use-zip} and \option{--use-zip-help} in |
| \command{R CMD INSTALL} are no longer available and |
| \option{--auto-zip} only zips data (or not). |
| |
| Help in packages installed under 2.9.x may not work correctly, |
| and a warning is given when such a package is attached by |
| \code{library()}. Re-installation of all packages is strongly |
| recommended (use \code{update.packages(checkBuilt = TRUE)}). |
| |
| Binary packages are installed without CHM help if they contain |
| it (as those intended for 2.9.x may). |
| |
| \item It is possible to install source packages without Rtools |
| provided they have no compiled code and no \file{configure.win} or |
| \file{cleanup.win} script. |
| } |
| } |
| \subsection{INSTALLATION}{ |
| \itemize{ |
| \item Support for memory profiling is enabled in a standard build |
| (this can be changed by editing \file{config.h}). |
| |
| \item CHM help is no longer supported. |
| |
| \item The help default for the standard installer is HTML help rather |
| than CHM help. |
| |
| \item The categories in the installers have been simplified. Now the |
| files to support installation of source packages are always |
| installed (they are now only 0.7Mb), and there are no longer |
| categories 'chtml', 'html/help', 'latex' and 'Rd'. |
| |
| |
| } |
| } |
| \subsection{BUG FIXES}{ |
| \itemize{ |
| \item \command{Rcmd open} now works as documented: previously |
| \command{Rcmd open.exe} was required. |
| |
| \item \code{cat(x, file=)} in \command{Rgui} tried to interpret |
| UTF-8-encoded strings for the console rather than converting them |
| to the native encoding. |
