Hello, i'm trying to draw a dendrogram to show the clustering hierarchy. i'm working on 2 classes but each class contains more than 3000 instances. i'm using the hclust function to do that! but i can't read anything from this figure. i would like to color each class with its own color so at least i can extract some information from the clustering. does any one of you did something like this before? Regards, Ayoub.
