Well, ?image and ?heatmap (! what else?) can do this -- except that
you probably want this on some sort of map projection, right? Assuming
that's the case, check the "spatial" task view on CRAN and/or post on
the r-sig-geo list . I am sure there are many packages that can do
various flavors of this.
