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.
