[R] coloring agnes plots

[Raymond Wan]

Hi all,

I am creating dendrograms using agnes and was wondering if it is 
possible to add color to the leaves (and just the leaves).

For example, in the documentation, they have an example using the 
"votes.repub" data set.  If I wanted to make the word "Washington" green 
(and only Washington), is it possible and if so how?

I can apply "summary" to the object created by agnes and even see the 
names of the objects:

Order of objects:
  [1] Alabama        Georgia        Arkansas       Louisiana 
Mississippi
...

but I don't know how to designate colors to the objects...

Thank you!

Ray
