Subject: s.voronoi and r.linear.regression

We are looking for source code which will compile on a sun
sparc station for s.voronoi (our copy doesn't do anything
but spit out errors) and r.linear.regression (we can't
find this anywhere). Can anyone help?

We know that s.voronoi is supposed to be replaced by
v.geom, but v.geom works on vector files while s.voronoi
works on site files. Geom only does Delaunay triangulations
while voronoi does Distichlich tesslelations (which are
what we want!)

Thanks in advance.

Does s.geom not do what it's advertized?

|\fIs.geom\fR \- Computes Delaunay triangulation, MinMax-Angle triangulation,
|MinMax-Slope triangulation, MaxMin-Height triangulation,
|Regular triangulation, planesweep triangulation,
|Voronoi diagram, and convex hull of sites in 2 and
|2 1/2 dimensions.

Note: voronoi diagram = dirichlet tesselation
