of course you mean the contrary: reprogram stats:::plotNode() to
use a *non*-recursive algorithm {"iterative" as you say in the 'Subject' line}

Yes, please, patches are very welcome -- if they are tested.
Please start from
https://svn.r-project.org/R/trunk/src/library/stats/R/dendrogram.R
i.e. send patches with respect to that,
i.e., the result of
diff -ubBw <old-dendrogram>.R <new-dendrogram>.R
With thanks in advance,
Martin Maechler
