Thanks for getting back to me Pablo.  I think that we had previously 
established that image() --- which is what you would use to plot the 
object returned by kde2d() --- did produce non-blank plots for you when 
properly applied to "im" objects on your computer.  But somehow when 
image() gets applied inside plot.im() something mysterious --- in fact 
downright impossible!!! --- happens and no plot is produced.

The mystery remains.

cheers,

Rolf
