public class JGR
extends java.lang.Object

JGR, Java Gui for R JGR is just a new Gui for R http://www.r-project.org , written in Java.
Thus it is (should) be platform-indepent. Currently we have several problems on *nix machines.

JGR uses JRI and rJava for talking with R, and the JavaGD- Device all written by Simon Urbanek.
