[R] Color code leaves on dendrogram

[Wade Wall]

Hi all,

I would like to color code the leaves on a dendrogram to reflect group
membership.  Does anyone know of a function to do this besides code
listed at http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=79?
 I haven't seen anything recently to accomplish this.  I basically
just want to color code sample (leaf) labels.

Thanks for any help.

Wade
