[R] slow graphics download

[Paul Murtaugh]

Hi,

I often work from home, running R on my office computer and displaying 
interactive graphics on my home computer using X11.  This was always 
more sluggish than sitting at my office computer, obviously, but 
recently the graphics transfer has become painfully slow -- so slow, 
that I now divert the images to a postscript file and display that file 
remotely (which takes a second or two).

I don't know what changed between the old days and now -- I may have 
installed a new version of R and updated the o.s. (ubuntu) on both 
computers, but am unsure of the timing.  I realize this makes 
troubleshooting difficult, but I am hoping someone can offer a tip on 
where to begin.

Thanks
-Paul
