Spatially constrained hierarchical clustering, any news?
Hi List, is there any news regarding a spatially constrained hierarchical clustering algorithm implementation in R? I found this post from 2005 http://finzi.psych.upenn.edu/R/Rhelp02a/archive/56819.html but nothing that really helped. I also found the package 'rioja' http://cran.r-project.org/web/packages/rioja/rioja.pdf which contains some constrained hierarchical clustering but that's not what I needed. I'd like something with the interface of 'hclust' (read: dissimilarity matrix) but which also allows in each step of the clustering to specify somehow which of the clusters must not be merged. Before I start digging into the hclust sources, I thought I'd rather ask. Regards, Georg.
