Spatial Clustering in R

Hi Dan.  The attributes are not distances nor any type of
similarity/dissimilarity measure, but rather actual attributes of
individual spatially referenced items (specifically, continuous and
categorical measures of tree attributes, e.g. diameter and taxon).  Thanks.

And by the way the correct terminology appears to be either spatial
segmentation or spatial regionalization, not the "spatial clustering" that
I used in the subject line of my original post.  I don't mean to refer to
the spatial analysis of the points themselves, but rather to the ATTRIBUTES
of the items at those points.

Hi Jim,

What are the nature of the attributes of the items, are they simply
actually distances from one another, or is their some other measures of
similarity/dissimilarity (say differences in soil types)?
