⚠️ JGR was mainly developed during my study time until 2006. Back then my programming skills where just coming up and evolving, that's why the code looks like it looks.

JGR (speak 'Jaguar') is a universal and unified Graphical User Interface for R (it actually abbreviates Java Gui for R). JGR was introduced at the useR! meeting in 2004 and there is an introductory article in the Statistical Computing and Graphics Newsletter Vol 16 nr 2 p9-12

1. Install R from r-project.org

2. Install packages from within R install.packages('JGR',,'http://www.rforge.net/')

❗ it also contains code from RoSuDa Java package which is based in module ibase to be totally self-contained and have no dependency to iPlots anymore. As well as JavaGD to be able to compile.
