Implement 'tableGrob' object as a clickable image map. The 'clickableImageMap' package is designed to be more convenient and more configurable than the edit() function. Limitations that I have encountered with edit() are cannot control (1) positioning (2) size (3) appearance and formatting of fonts In contrast, when the table is implemented as a 'tableGrob', all of these features are controllable. In particular, the 'ggplot2' grid system allows exact positioning of the table relative to other graphics etc.
