[R] Dendrogram for a type unbalanced ANOVA

Hi-

I have about 20 groups for which I know the mean, variance, and number of points per group. Is here an R function where I can plot (3 group example) something like

| |----- 2
| |-----------|
| | |----- 1
| |
|------|
| |----------------- 3
|
|
0 25 50 75 100

ie 1 and 2 are different at 75% level of confidence

   1 2 combined are different from 3 at 25% level of confidence

If this plot is a silly idea can someone point me to a reference for anything similar?

Thanx
