R(1)

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 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.

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 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''.
