[R] Need frequency distribution for x,y coordinates

Hi,

I have a set of data in x,y coordinates across the range of -5 to 5 in each dimension. I would like to obtain the frequency distribution of the different points, and then graph them so you can see which of the points are the most frequently occurring.

This would seem to be easy in Matlab, which has the hist3 command for doing frequency distributions/histograms in 3 dimensions. However, as far as I can tell, R does not have a hist3 command.

Is there any easy way to do this in R? I'm investigating whether matlab or R is more suitable for our needs, but don't want to reject R due to my present ignorance of its functions.
