[R-sig-Geo] Filtering a set of points by minimum distance between them

[Arnald Marcer]

Hi,

I have a set of coordinates in utm and need to get a subset of
them in which any coordinate is at a minimum distance from
any other one, that is to say, I need to filter them according
to a minimum distance between them.

Is there a function to do that or should I try to code it myself ?
Is there also a way of introducing randomness in the sense that
any run will give me a different set ?

Any help would be much appreciated

Thanks
