The most powerful statistical computing language on the planet.

R is a programming language and environment to work with data. It is loved by statisticians and data scientists for its expressive code syntax and plentiful external libraries and tools and works on all major operating systems.

The R language is easily extensible with packages written by a large and growing community of developers around the world. You can find it pretty much anywhere—it is used by academic institutions, start-ups, international corporations and many more.
