The HTKIdentify (requires tcltk package) and HWIdentify (windows only)
functions in the TeachingDemos package will show identifying information on
a plot for the point being hovered over.  Both functions are pure R code,
so if they don't work for you as is you can modify the source to make
whatever tweaks you may want.
