[BioC] Color in the lefs of a dendrogram?

[Johan Lindberg]

Hi all. I have a question of how to put color in a plot of a
hierarchical clustering that I have done with 24 microarrays in an
experiment. The basic code that I use to plot:
 
sampdist <- dist(t(Mmatrix), method="euclidean")
sclus <- hclust(sampdist, method="average")
plot(sclus, cex=0.7)
 
With the argument labels = NULL I can control the names of the leafs but
is there some way of giving the different leafs different color? Ive
tried the usual
 
col.axis
col.lab
col.main
col.sub
col
 
But none seem to work. Ive also looked into the helpfile of plot.hclust
but nothing seems to be noted there. It would really be great to be able
to put color to the leafs to facilitate visualization. 
 
What I am doing now is to save the image as a postscript and change the
postscript file manually. But that is no fun :(
 
Help, someone?
 
Best regards
 
// Johan
