Here's something I did a few years ago that lets you create PNG files 
and an HTML imagemap

  It might be tricky to add clickable areas to plots drawn by other 
functions and packages, since you dont know exactly where the points 
are, but with access to the source code that should be fixable.

  For example, suppose you wanted to make the box of a boxplot 
clickable, you need to know the coordinates of the box on the graphics 
device. If the return value and parameters to boxplot dont give this 
information, you'll have to work it out.
