R is a programming language for statistical computing known for its rich ecosystem of 3rd party libraries called “packages”. The R language is typically used for statistics, data mining, analysis and visualization, machine learning, and similar tasks. However, R remains, at least in essence, a general purpose language that can be, for example, used for reactive web applications development through the Shiny framework.

FastR is a GraalVM based implementation of the R language that provides significant improvements in the performance of R code, the embedding of the R execution engine into Java applications, and the ability to interface with other GraalVM and JVM languages including Python, Java, and Scala. FastR is also able to utilize the tooling support provided by the GraalVM ecosystem.
