Although, after spending several using Linux, you learn to prefer command line stuff over GUIs, they can still be nice to have, especially for programs you use rarely or if you’re a newbie. So for those you, for example, who want to migrate from Windows to Linux, and are not comfortable using command line, there is a nice R GUI, written in JAVA, that works well for linux, at least it was a breeze installing on my Ubuntu 8.10. It’s called JGR (Java GUI for R) and you can read about how to install it (and R and Java as well, although be aware that there are regularly new version of those so google recent guides on how to install those on your system) here http://jgr.markushelbig.org/JGR_on_Linux.html
