This package is a metapackage which eases the transition from the pre-1.5.0 package setup with its larger r-base package. There is also a large set of functions which provide a flexible graphical environment for creating various kinds of data presentations.Īdditionally, several thousand extension "packages" are available from CRAN, the Comprehensive R Archive Network, many also as Debian packages, named 'r-cran- '.
The R distribution contains functionality for a large number of statistical procedures and underlying applied math computations. It is possible for the user to interface to procedures written in the C, C++, or FORTRAN languages for efficiency, and many of R's core functions do so. Most of the user-visible functions in R are written in R. The core of R is an interpreted computer language which allows branching and looping as well as modular programming using functions. Whereas the resulting language is very similar in appearance to S, the underlying implementation and semantics are derived from Scheme. The design of R has been heavily influenced by two existing languages: Becker, Chambers & Wilks' S and Sussman's Scheme.
It consists of a language plus a run-time environment with graphics, a debugger, access to certain system functions, and the ability to run programs stored in script files. R is a system for statistical computation and graphics.
