Dear R-users, I recently started programming in R in order to implement Voronoi diagrams (without weights) and to modify them afterwards. I used the "deldir" package. I'm looking now for a possibility to implement additive weighted Voronoi diagrams. Does anyone has experience in adapting the deldir package (I suppose that I have to modify some of the Fortran-subroutines)? Is there another possibility to create an additive weighted Voronoi diagram? I thank you sincerely for your help, Cathleen
