I'm wondering whether any R package has the ability to perform spatial clustering, i.e. the spatial partitioning of a data set into relatively homogeneous polygons, based on one or more attributes of the items (similar to what the program eCognition does). Perhaps there is a more statistically correct term for what I have just described, but I don't know it. Thanks.

You may like to look at the implementation of SKATER included in spdep
thanks to Renato M. Assuncao and Elias T. Krainski, see ?skater. The
underlying reference is:

Hope this helps,
