R [options] [< infile] [> outfile]
RCMD command [arguments]
DESCRIPTION
Start R, a system for statistical computation and graphics, with the
specified options, or invoke an R tool via the 'R CMD' interface.
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.
On platforms which support the dlopen(3) interface, Fortran and C
code can be linked and called at run time.
On systems which have the GNU readline(3) library, R will maintain
a command history, so that commands can be recalled, edited and
re-executed.

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.
Start R and type ?topic at the R prompt to obtain on-line
information for `topic'.
If the processed manuals have been installed they will be available as
DVI and/or PDF files in the directory `R RHOME`/doc/manual.
If the info program and the R manuals are installed on your
system, typing info -f R-intro, info -f R-data,
info -f R-exts,info
-f R-FAQ and info -f R-lang 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''.
