Derek (and others),
I've kinda, sorta got the voronoi() function working, but I have a
related query for now. If I run the function on "n" points, shouldn't
I get "n" polygons?
I have a table with 1597 points, but when I ran the function, I got
1595 polys, and am wondering what the heck happened to two of them?
Coincident point?

create or replace function voronoi(text,text,text) returns setof
voronoi as ' library(deldir)
# select the point x/y coordinates into a data frame...
