|
|
R is a system for statistical computation and graphics. 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.
|
|
|
|
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. The R distribution contains functionality for a large
|
|
number of statistical procedures. Among these are: linear and generalized
|
|
linear models, nonlinear regression models, time series analysis, classical
|
|
parametric and nonparametric tests, clustering and smoothing. There is also
|
|
a large set of functions which provide a flexible graphical environment for
|
|
creating various kinds of data presentations. Additional modules ("add-on
|
|
packages") are available for a variety of specific purposes.
