{{#invoke:Hatnote|hatnote}} {{ safesubst:#invoke:Unsubst||$N=Use mdy dates |date=__DATE__ |$B= }} R is a programming language and software environment for statistical computing and graphics. The R language is widely used among statisticians and data miners for developing statistical softwareUnknown extension tag "ref" and data analysis.<ref name=nytimes09/> Polls, surveys of data miners, and studies of scholarly literature databases show that R's popularity has increased substantially in recent years.Unknown extension tag "ref"

R is an implementation of the S programming language combined with lexical scoping semantics inspired by Scheme.<ref>{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref> 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<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> 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.<ref>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref>

R is a GNU project.Unknown extension tag "ref" The source code for the R software environment is written primarily in C, Fortran, and R.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> R is freely available under the GNU General Public License, and pre-compiled binary versions are provided for various operating systems. R uses a command line interface; there are also several graphical front-ends for it.
