I have a matrix of GPS coordinates. I would like to create a histogram with bins showing how many corrdinates are 1 meter apart, 2 meters apart, etc. Is there an available function to do this? Alternatively, does anyone have an approach to doing this?
Thank you much.

I think you just need to compute all of the pairwise-distances, and then you can create a histogram of the resulting matrix. The relevant functions are:

Beware that the pairwise distance output will have m(m-1)/2 elements, which may be terrifyingly large depending on your dataset.
