R - Man Page

R [options] [< infile] [> outfile]
R CMD command [arguments]

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.

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.

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”.
