Dear Elai, thank you very much for your suggestion. I tried cutting the dendrogram instead of the hclust tree with: clusters<-cut(x, h=1.6)
but then when I try to call/plot cluster 1 for example, with: plot(clusters$lower[[1]]) I get only 2 members that are joined together at distance=0 (cluster 1 for instance, consists of several hundred of members). So it looks like / plot(clusters$lower[[1]])/ only calls the very first node of the tree and not the content of the respective cluster [[1]] at the defined cutoff=1.6. Maybe /cut/ instead of /cutree/ doesnt do the work? Or maybe I am just doing something wrong?... In another post I read that with /df[value %in% v, ] / I can extract specific subsets of a data frame/table. Maybe I could use this to extract only the distances of members of a specific cluster as defined by cutree from the initial distance matrix? But still, I am afraid I don't get what I should use as /value/ and /v/.... -- View this message in context: http://r.789695.n4.nabble.com/Advice-on-exploration-of-sub-clusters-in-hierarchical-dendrogram-tp4414277p4415589.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
