Alexey,
See ?dist.nodes in ape. If your tree is named tr, you'll get exactly
what you want with:
dist.nodes(tr)[, Ntip(tr) + 1]
which extracts one column of the matrix returned by dist.nodes.
best,
Emmanuel

Hi Alexey.
If you want the set of internal node heights for an object of class
phylo (these will also be the distances from the root), you can use:
library(phytools) ## must be =0.4-05
h-setNames(sapply(1:tree$Nnode+length(tree$tip.label),nodeheight,tree=tree),
