| R is a language which bears a passing resemblance to the S language |
| developed at AT&T Bell Laboratories. It provides support for a variety |
| of statistical and graphical analyses. R is a true computer language |
| which contains a number of control-flow constructions for iteration and |
| alternation. It allows users to add additional functionality by |
| defining new functions. |
| .LP |
| On systems which have the GNU \fBreadline\fP(3) library, R will maintain |
| a command history, so that commands can be recalled, edited and |
| re-executed. |
| |
| [OPTIONS] |
| |
| Most options control what happens at the beginning and at the end of an |
| R session, in particular which files are being read and written, and how |
| much memory is reserved for the R process. |

| [SEE ALSO] |

| The full documentation for R is provided by a collection of Texinfo |
| manuals and individual help for R objects which is also available |
| on-line. |
| .LP |
| Start R and type \fB?\fP\fItopic\fP at the R prompt to obtain on-line |
| information for `\fItopic\fP'. |
| .LP |
| If the processed manuals have been installed they will be available as |
| DVI and/or PDF files in the doc/manual subdirectory of the documentation |
| directory tree (default `R RHOME`). |
| .LP |
| If the \fBinfo\fP program and the R manuals are installed on your |
| system, typing |
| \fBinfo -f R-intro\fP, |
| \fBinfo -f R-data\fP, |
| \fBinfo -f R-exts\fP, |
| \fBinfo -f R-FAQ\fP, |
| \fBinfo -f R-lang\fP and |
| \fBinfo -f R-ints\fP |
| should give you access to |
| ``An Introduction to R'' |
| (the basic manual), |
| the ``R Data Import/Export'' Guide, the ``R Extension Writer's Guide'', |
| the ``R FAQ'', the ``The R Language Definition'', and the ``R Internals''. |
