The R language has been in the community since the 90's (even though it was developed a decade before). With its open source GNU license, R gained popularity for its no-fuss installation and ability to evoke any available package for additional statistical learning functions. This was a clear advantage to R as there were not that many statistical programs available on the market in the '80s and '90s; in addition, most of them were not free. The extensibility with emerging new packages for the core R engine gave a broader community and users more and more abilities to use the R language for multiple purposes, in addition to its strong statistical analysis and predictive modeling capabilities.
