[BioC] problem with hclust

[shannon]

Hi

dendrograms were designed for and intially applied to significantly
smaller problems then 2,000 objects. I cannot imaging how to dispaaly a
tree with that many terminal nodes in such a way to be able to read the
labels.

You might try using 'cutree' into a dozen or so subtrees and plot each
subtree individually.

You might also try using kmeans to partition the data with that large a
sample.
