[R-sig-Geo] offsetting overlapping points

[MacQueen, Don]

I don't know of a function for precisely what you're looking for, but in
the "roll your own" department, have you looked at the jitter() function?

You would probably have to run it separately on x and y, and tinker with
its arguments that control the offset. But it certainly should be doable.
