Dear friends,
I can't find the functions in R to do the following tasks:
1. extract the coordinats of ploygon's center ;
2. create Dirichlet tessellation and Delaunay triangulation for a set of
points
sp,spdep,tripack,et al, seem not to be able to finish it.
If u know how to do it, please let me know.
Thanks very much.
