*R* is a programming language and software environment for statistical
computing and graphics supported by the R Foundation for Statistical
Computing.^[3] The R language is widely used among statisticians and data
miners for developing statistical software^[4] and data analysis.^[5]
Polls, surveys of data miners, and studies of scholarly literature
databases show that R's popularity has increased substantially in recent
years.^[6]

R is an implementation of the S programming language combined with lexical
scoping semantics inspired by Scheme.^[7]S was created by John Chambers
while at Bell Labs. There are some important differences, but much of the
code written for S runs unaltered.

R was created by Ross Ihaka and Robert Gentleman^[8] at the University of
Auckland, New Zealand, and is currently developed by the /R Development
Core Team/, of which Chambers is a member. R is named partly after the
first names of the first two R authors and partly as a play on the name of
S.^[9]

R is a GNU project.^[10] The source code for the R software environment is
written primarily in C, Fortran, and R.^[11] R is freely available under
the GNU General Public License, and pre-compiled binary versions are
provided for various operating systems. While R has a command line
interface
