Maybe the Voronoi and Delauney triangulations demo at
http://xerxes.sph.umich.edu:2000/Rweb/Rweb.general.html
would get you started.
... regarding a message from Ranjan Maitra on Dec 18:
> Dear list,
>
> I have five points on an unit square and I would like to be able to
> draw the Voronoi polygons (similar to Delaunay triangulation/Dirichlet
> tesselation) with these. Can this be done in Splus/R using linux?
> There is some code on Statlib by Rolf Turner but that uses ratfor
> which I don't have.
>
> Many thanks and best wishes,
> Ranjan
