[R] panel.levelplot() for 2D histograms

Dear R-wizards, I'm trying to plot "binned scatterplots", or 2d histograms, if you wish, for a number of groups by using the lattice functionality it works fine for one group at a time, and probably I could find a work-around, but I prefer to do it the elegant way here's an example of what I want,

Hi, I know this question has been posed before, but I didnt find the answer in the R-help archive, so please accept my sincere apologies for being repetitive: How can one (elegantly) calculate the distance between data points (in the transformed space, I suppose) and the hyperplane that separates t
