The R Project for Statistical Computing (R) is a free software
environment for statistical computing and graphics.
R provides a wide variety of statistical (linear and nonlinear
modelling, classical statistical tests, time-series analysis,
classification, clustering, ...) and graphical techniques, and is
The S language is often the vehicle of choice for research in
statistical methodology, and econometrics, and R provides an Open
Source route to
participation in that activity.

Notes on the R programming language, R_note,
R is an integrated suite of software facilities for data
manipulation, calculation and graphical display. It includes:
- An effective data handling and storage facility,
- A suite of operators for calculations on arrays,
in particular matrices,
- A large, coherent, integrated collection of
intermediate tools for data analysis
- Graphical facilities for data analysis and display either
on-screen or on hardcopy, and
- A well-developed, simple and effective programming
includes conditionals, loops, user-defined recursive functions and
input and output facilities.
One of R's strengths is the ease with which well-designed
publication-quality plots can be produced, including mathematical
symbols and formulae where needed.
R, like S, is designed around a true computer language, and it
allows users to add additional functionality by defining new functions.
Much of the system is itself written in the R dialect of S, which makes
it easy for users to follow the algorithmic choices made.
Although R is mostly used by statisticians who need an
environment for statistical computation and software development, it
can also be used as a general matrix calculation toolbox with
comparable benchmark results to Octave
and its proprietary counterpart,
(version < 7).
There are a number of excellent graphical frontends for R. You
can view our favourites at 7
of the Best Free Graphical User Interfaces for R.

R also features in our 'Linux
Equivalents to Windows Software' section. The category
selector below allows you to filter the different types of software
included in that separate article.
