Try the various Java devices at www.rosuda.org, or now rforge.net. A lot of
that was already in the latest Quantian, and it has also gotten easier on
Debian / Ubuntu thanks to the packages Sun Java and R's new R CMD reconfjava.
Just to see how painful it would be to do, I also added mouse tracking to
something with R's tcltk a few years ago. But I'm no gui hacker so...

Somewhat, as we know, as the base R graphics are static. But with Java you
can do some tricks. I also hope that svg device will help for zooming etc.
