It will be possible in the next versoin of R,
and soon in "R-devel" --
myhcl <- hclust(..........)
myd <- as.dendrogram(myhcl)
i.e. working with the dendrogram (and its plot method) rather
than with the original "hclust" object and its much less
flexible plotting method.
Since the needed changes only need R-code changes, you
can ask me "off line" and I'll send you the R code needed.
