What part of the plots do you want clickable? Lines are normally a bit
thin for clickable imagemaps...
I wrote a library to help me produce imagemaps from R code, its here:
http://www.maths.lancs.ac.uk/Software/Imagemap/
along with an example.
I wrote the code a while ago, and I can't remember how it works, and
you need the png() graphics device - which needs an X11 display, so its
tricky to do this from a console or server application. You need to let
it talk to an X virtual frame buffer in this case.
The tricky bit, I recall vaguely, was mapping device coords to pixel
coords on the PNG device.
Good luck...
