Hi,
I automatically create some R matplots and now I would like to automatically create HMTL image maps and make the plots clickable.
Do you have any suggestions how to do this?
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...
Baz
