Hello,
I have an unrooted tree, but I know that basal dichotomy is between nodes
labeled 174 and 500. I am wandering how to indicate it in the object of
class 'phylo'. I tried 'root' function of 'ape' but with no success.
I will be grateful for any advice. Best wishes

In my phytools package
(http://cran.r-project.org/web/packages/phytools/index.html) there is a
function reroot() that is really just a simple wrapper around root()
that allows you to root along internal or terminal edges (rather than
only at nodes).
In your example, assuming that the node
Dear Ondrej,
there is also a function midpoint in phangorn, which roots the trees
in the middle of the longest path. Maybe you are lucky and your edge
(500, 174) is one in the middle.

Klaus

All the best

approximating a multivariate based statistics.
so far, I understand the multiple R2 for a univariate response (and
