Abstract

The R package jsr223 is a high-level integration for five programming languages in the Java platform: Groovy, JavaScript, JRuby, Jython, and Kotlin. Each of these languages can use Java objects in their own syntax. Hence, jsr223 is also an integration for R and the Java platform. It enables developers to leverage Java solutions from within R by embedding code snippets or evaluating script f iles. This approach is generally easier than rJava’s low-level approach that employs the Java Native Interface. jsr223’s multi-language support is dependent on the Java Scripting API: an implementation of “JSR-223: Scripting for the Java Platform” that defines a framework to embed scripts in Java applications. The jsr223 package also features extensive data exchange capabilities and a callback interface that allows embedded scripts to access the current R session. In all, jsr223 makes solutions developed in Java or any of the jsr223-supported languages easier to use in R
