I have a hclust object that looks like this:
> test77
Call:
hclust(d = input)
Cluster method : complete
Number of objects: 11
> test77$height
[1] 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000 0.0000000 0.9000000
[8] 0.9473684 1.7894737 8.5771948
> test77$merge
[,1] [,2]
[1,] -1 -2
[2,] -3 1
[3,] -7 2
[4,] -8 3
[5,] -4 -6
[6,] -5 -10
[7,] -9 5
[8,] -11 4
[9,] 7 8
[10,] 6 9

I am specifically interested in what happens when you divide this
object into three clusters. When I look at the plot, the three
clusters form like this: (monospace font)
----------
| |
| ----
| | |
2 3 6
What I am wanting is to get distance information on the three groups,
and also the number of objects in each. The distances I need are in
height, but I don't know how to get at the sizes of the subtrees.
I know I can use cutree to get at the cut, but I cannot see anything
systematic in which group becomes group no 1 and so forth.
The results I want would in this example be:
2 3 6 8.5771948 1.7894737
Any hints for me?
Thanks!
Karin
