The design of R has been heavily influenced by two existing languages: Becker, Chambers & Wilks' S and Sussman's Scheme. Whereas the resulting language is very similar in appearance to S, the underlying implementation and semantics are derived from Scheme.
The core of R is an interpreted computer language which allows branching and looping as well as modular programming using functions. Most of the user-visible functions in R are written in R. 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. The R distribution contains functionality for a large number of statistical procedures and underlying applied math computations. There is also a large set of functions which provide a flexible graphical environment for creating various kinds of data presentations.
Additionally, over thousand extension "packages" are available from CRAN, the Comprehensive R Archive Network, many also as Debian packages, named 'r-cran-<name>'.
This package provides a patched version of GNU R with 'just-in-time' compilation of R code using the 'jit' package (in r-cran-jit). See http://www.milbo.users.sonic.net/ra for details.

README for Ra ------------- The file ra/NOTES has some additional documentation. The "ra" directory under the R root contains some Ra specific bits and pieces, including this file. Grep for "RA_TODO" in the sources for things that need attention. Summary of the process used to build Ra from the sources: a. Copy the R-2.9.2 sources into a new directory b. Install the "jit" package into more»
r-base for DEBIAN ---------------------- This Debian package was created from the sources on the Comprehensive R Archive Network sites. The master site is http://cran.r-project.org/ Douglas Bates <email@example.com>, Wed, 10 Dec 1997 14:17:31 -0600 The executable is called R. In accordance with the Debian package policy, the executable, /usr/lib/R/bin/R.binary, has been stripped. Trying to more»
