Dear Sarah,
ultrametric means that each tip of a tree has the same distance from
the root. hclust - upgma is a "average linkage" - always produces such
trees.
There is quite some irony that in phylogenetic reconstruction often
non-ultrametric methods are preferred, even though the time to the

Dear all,
I've stumbled upon a phylogeny problem I can't seem to solve with R, and I'm
hoping that someone could help me with that.
I have two datasets of the same samples: one with a few specific gene sequences
and one with expression data for a huge set of genes (almost 3000). I want to
creat
