Thanks for the direction!

Everything is enabled, but still doesn't work.
xeyes and xclock give errors (Error: Can't open display: localhost:10.0),
R produces Rplots.ps

I also have a windows box, and go to chena using PuTTY.
I have cygwin with X server installed on it.
If I enable X11 forwarding in PuTTY, start cygwin's X11 server on Windows and 
try to run xeyes or xclock, I see their windows on my local MS Windows desktop,
R still produces Rplots.ps.

Will try to catch sysadmins and fix the things with them (I don't have the root 
access to everything, unfortunately).
