[R] Is there any method to do spatial sampling?

[Marshall Feldman]

What kind of spatial sampling do you want to do: systematic, stratified,
simple random, etc.? What will you be sampling: points, lines, polygons,
etc.?

Subject: [R] Is there any method to do spatial sampling?

I have a map of a district (which is JPG format), and I want to do a
sptial sampling based on the map. So is there any function to do
spatial sampling of this type?

Thanks!
