.SH NAME
R \- a language for data analysis and graphics
.SH SYNOPSIS
.B R
[\fIoptions\fR] [\fI< infile\fR] [\fI> outfile\fR]
.br
.B R
\fICMD command \fR[\fIarguments\fR]
.SH DESCRIPTION
Start R, a system for statistical computation and graphics, with the
specified options, or invoke an R tool via the `R CMD' interface.
.PP
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 platforms which support the \fBdlopen\fP(3) interface, Fortran and C
code can be linked and called at run time.
.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.
.SH 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.

.SH "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 directory `R RHOME`/doc/manual.
.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 and \fBinfo -f R-lang\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'' 
and the ``The R Language Definition''.
