R − a language for data analysis and graphics
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.

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’’.
