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 de-
veloped 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 defin-
ing 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-exe-
cuted.

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.

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 documenta-
