dear group members,
I am looking for a function that assess the stability of cluster. The result of hclust function is an hclust object which can  be plot as a dendrogram. However to have confidence in the tree topology usualy bootstap is applied. I understand that I can apply bootstarp on the original data and then run hclust(dist() ) as much as I resampled but how to comapre the topologies the I don't know. Is there a bootstarp or permutation for cluster?
thanks,
Ron
