fantastic.  for now some of this R and statistics is over my head!  i'll
have to spend some time getting orientated.  thank you for the links.

is this part below, referring to my previous question to cluster one mass of
points around an other set of points that are much less? (eg, 50 points and
how to cluster them around 3 points from another layer)

clustering around set "medoids" with pam() or set "centroids" with
kmeans() is fairly simple, just see the documents associated with
these functions. the CRAN website will be a good start. also, for some
rather generic R examples and documents see the link:
http://casoilresource.lawr.ucdavis.edu/drupal/node/100

I would love to post my steiner results.  maybe i can do the same thing on
spearfish data because the data i used is client specific.  I'll make a run
on the spearfish60 data, and provide a step by step walk through.
