Hi, I try to get the vector of leaf's names from object "dendrogram" generated by cut(). For example, I have a matrix mat(100*10) rownames(mat) <- 301:400 dianaGenes <- diana(mat) mydendrogram <- as.dendrogram(as.hclust(dianaGenes)) dianaClusters.h3 <- cut(mydendrogram,h=3) >From here, I tried to get the vector of leaf's names of subtree( which are corresponding to rownames of mat) from dianaClusters.h3$lower[[3]], but I couldn't figure it out. Then I can use this vector to subset original matrix mat. Any help is appreciated. Thanks, Ren [[alternative HTML version deleted]]
