JGR on Snow Leopard
Download 64-bit JGR launcher from Download Page (JGR-1.6-SL.dmg).
Below information is depraceted since R package includes 64-bit version.
To answer all those recent posts on both mailing lists regarding JGR on OS X 10.6 (Snow Leopard) and R 2.9.x:
You need 64-bit R to run JGR, because Apple has removed 32-bit Java from OS X 10.6. So follow those steps:
Install 64-bit R from http://r.research.att.com/
Install necessary packages as follows:
install.packages(c("rJava","JavaGD","iplots"))
install.packages("JGR",type="mac.binary")
Run the launcher and enjoy.
