Hello, I have another question about heatmaps... I would like to get a heatmap only from a part of the cluster (right now, it is impossible to read the labels). I got the dendrogram sub-trees using the cut function (subtrees <- cut(cluster, h=1)). Now, before giving each subtree to heatmap, I guess I have to select the corresponding data from the matrix (i.e., the probes that are included in each sub-tree), how can I get the leaves/members of each subtree (subtrees$lower[[i]])? or alternatively, how can I partion what is shown in a heatmap while keeping the ordering of the cluster? Thanks! Lourdes
