J4R is a technology developed by Mathieu Fortin (Canadian Wood Fibre Centre) to call Java programs from R. It tries to be simpler to use than other technologies including rJava. J4R is based on a client/server architecture, with a server running transparently Java on your local machine. In the latest version of J4R, the server can run on a remote machine allowing for multiple client connections.

Details and resources:

• J4R does allow to call R from Java.
• J4R is compatible with Java 1.8 (and later), which runs Capsis.
• The reference publication by Mathieu Fortin is here.
• The link to J4R in SourceForge, with installation and usage detailled explanations, you may start from here.
