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,
