[R] Bin by bin histogram comparisons

[Philipp H. Mohr]

Hello,

I have created two histograms with:

	 hist2d(gps2, nbins=200, col = c("white",heat.colors(16)))

Both of them have the same range and the same number of bins.
Now I would like to compare them bin by bin and plot the results.
Could someone please tell me how to do that. I searched the man pages and
the web, but couldn't find anything.

Thank you very much.

Phil
