Dear R-Help,
I am trying to get JRI (the rJava interface allowing Java to connect
to R) to work. I was able to run it a week ago when I was doing some

R GUI installation on Linux/SuSE 10.3
After a long sufferance I had succeeded in installing R GUI on my
Linux/SuSE system. It worked fine.

I have R running back with text interface. I tried to get the nice R GUI up
& running again. I followed all the steps to reinstall the R GUI but this

Getting JRI/rJava to work
Hello All
I am trying to get the JRI examples from rJava to work on Windows XP and
failing. (And as a more general and connected question is there any
review/summary of front-end software for R?)
I have installed rJava from the Windows binary supplied. I compile and
run the example supplied (rtest.java) and get the results below. I do
not think the notes about a deprecated API are a problem. But
