Hi all! I am new to R. I have clustered the samples (columns) using hclust function. Since there are a huge number of samples, 291, the sample names in the cluster tree is cluttered. Please suggest if i can zoom the cluster plot or what else can I do? Please help! I used the following steps to cluster: >dist_sample <- as.dist(1-cor(exprs(eset)) >hc_samples <- hclust(dist_sample, method="average") >plot(hc_samples) Thanks in advance!

For this, you may want to explore the dendrogram documentation with '?dendrogram'. In your example, the zooming can be achieved by changing the xlim/ylim values in the following plotting command: plot(as.dendrogram(hc_samples), xlim = c(1,20), ylim = c(1,50)) Thomas On Sun, May 03, 2009 at 11:48:09PM +0530, dhaarini s wrote: > Hi all! > I am new to R.
