Hi all, My problem concerns cluster dendogram. For example, i obtain : h<-hclust(mat,method="ward"). I can plot the dendogram with: plot.hclust(h) This is my questions: 1- I would like to cut the tree and only display the part for which h$height is greater than 20 for example. 2- I would like to plot the dendogram for one class. More precisely, suppose that i have two classes for my classification How can i plot the dendograms for my two classes. I tried to use the tree libarary but with no success. Could you help me.
