FastR is an open-source high-speed implementation of the R programming language for statistics atop Truffle and Graal. Using that framework facilitates better performance in comparison to the standard implementation.
The FastR project aims at full compatibility with the standard implementation. This sets FastR apart from most of the existing standard R alternatives. To ensure compatibility, FastR applies unit testing. Currently, ca. 16,000 single unit tests covering a broad range of the language semantics are in use.
The project collaborates with academic groups at Northeastern University, Purdue University, JKU Linz, and TU Dortmund. FastR has also received contributions from UC Davis.
