R

With the rise of data science and statistical software, it’s only natural that a language as laser-focus as R would grow among the development ranks. Thanks to its wide array of libraries, R can implement a lot of statistical and graphical techniques, such as linear and nonlinear modeling, classification, clustering, and many others.

R is a programming language and free software environment for statistical computing and graphics supported by the R Core Team and the R Foundation for Statistical Computing. The R language is widely used among statisticians and data miners for developing statistical software and data analysis.
