Dear r-help mailing list, thanks for the advices on the last question,through them I've solved it. But now, I would know, how is possible to compare two(or more) cluster dendrograms, because for each cluster dendrogram coming from different data frame the height is measured with different unit of measure (not for the method -euclidean-that is the same),so the cluster dendrograms aren't comparable.How can I solve it? Thanks Cordially Alex
