[R] Additive Weighted Voronoi Diagrams

[Cathleen]

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
