NAME
R - a language for data analysis and graphics
SYNOPSIS
R [options] [< infile] [> outfile]
R CMD 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 systems which have the GNU readline(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.
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 doc/manual subdirectory of the
documentation directory tree (default ‘R RHOME‘).
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,
info -f R-lang and info -f R-ints 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’’.
