[R-sig-Geo] jitter within polygon

[Paul Lantos]

I am trying to figure out how to randomly jitter points within an overlying polygon structure.

I can easily jitter the points themselves, but I would like this to be constrained by the boundaries of polygons containing the points.

This isn't for visualization - I can do that easily enough in GIS. I actually need to generate coordinates.

Thanks,
Paul
