Maybe try this sampler - https://gist.github.com/obrl-soil/839b192da46978351733483421db22f8<https://urldefense.proofpoint.com/v2/url?u=https-3A__gist.github.com_obrl-2Dsoil_839b192da46978351733483421db22f8&d=CwMGaQ&c=imBPVzF25OnBgGmVOlcsiEgHoG1i6YHLR0Sj_gZ4adc&r=pCiIbVPBNWU0azo0D48ChUH_fawb-FalNVOf1sUn1r4&m=JsxKvUqShLm0BOKkwOldeOLeDanBw61LAAhZ6snUYW4&s=7U1IpidxWg5KFM1OLw0uCC1KWrtiHLMn9m0W6UfKPtQ&e=>

You’d want to run it multiple times and cycle through the outputs, if I’m interpreting your request correctly.

Subject: [R-sig-Geo] jitter within polygon

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
