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 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.

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.
