Hi,

I am  using hclust and cutree to cluster a data frame y and cut it into few
clusters as follows

y
  V1 V2 V3 V4
A  1  2  3  4
B  5  6  7  8
C  9 10 11 12
D 13 14 15 16
E 17 18 19 20
> clu<-hclust(dist(y),method="complete")
 clu<-hclust(dist(y),method="complete")
> clu
Call:
hclust(d = dist(y), method = "complete")
Cluster method   : complete
Distance         : euclidean
Number of objects: 5
> plot(clu)
> ct<-cutree(clu,k=3)
> rect.hclust(clu,3,border="red")
> ct
A B C D E
1 1 2 2 3
The question is how to plot the cluster number on the dendrogram plot?

Any help is appreciated.
