[R-sig-Geo] Spatially Constrained Clustering

[Carson Farmer]

Hello List,

I am trying to find an R package that will accommodate spatially 
constrained clustering.  While I have been unable to find a package that 
is explicitly designed to do spatially constrained clustering, I was 
wondering if anyone had found a package that would do constrained 
clustering of any kind, and adapted this to spatial constraints?
I have searched the R site extensively, and googled all night long, but 
to no avail! I HAVE found this post:
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/56819.html
but the replies did not help much.  They lead to several packages which 
perform spatial clustering (such that significant clusters of say a 
disease are located within a study region), however, what I would like 
to do is partition a spatial (grid) dataset based on multiple variables, 
taking into account their spatial locations (i.e. clustering is based on 
the variables, but constrained so that clusters are spatially 
contiguous).  I'm thinking mclust is probably the best way to go, but 
I'm not sure where to start.

Any suggestions would be greatly appreciated.

Thanks,

Carson
