Subject: R or C++ on FreeNX servers
In-Reply-To: <4B0D9BAC.7010800@waikato.ac.nz>
All FreeNX allows you to do is access a regular linux machine using X
over SSH as opposed to ssh'ing in, redirecting the X-display back to
your local machine (running a xserver locally)..
You can install R on the machine(s) just as you would normally, and if
the machines are in some sort of clustered environment, you could setup
the packages specifically available on linux for R to do that (snow,
multicore, etc...)
