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.
