Thank you for your reply Wolfgang
I've seen these examples but my problem is that I don't know how to
make the input data out of my given data. According to the example
below hclust is making the clustering and will result in hclust object
hc. In my case the clustering is already done and I need to create the
hclust object out of my clustering result. So I probably have to study
how to create the hclust object first..

dndrgr> hc <- hclust(dist(USArrests), "ave")
dndrgr> (dend1 <- as.dendrogram(hc))
