change individual label colours in a cluster plot?

Hi,

If you have a variable, that defines what you want to differentiate
(sociology, economics etc.) then you can add color depending on the
value of that variable. You will have to convert it to numeric if it is
not. An example would be

plot( iris[ , 1 ], iris[ , 2], col = iris[ , 3 ] )

Thank you.  I'm not sure that I can do that with an hclust object,
though: perhaps something using the text function and the order data in
the hclust object might work?

Currently, I'm good getting results using a script to edit the
postscript output, but I'm keen to find an R solution, if only to
improve my understanding of R graphicss.

Yours sincerely,
