This function computes the branching times of a phylogenetic tree, that is the distance from each node to the tips, under the assumption that the tree is ultrametric. Note that the function does not check that the tree is effectively ultrametric, so if it is not, the returned result may not be meaningful.
branching.times(phy)a numeric vector with the branching times. If the phylogeny phy
has an element node.label, this is used as names for the
returned vector; otherwise the numbers (of mode character) of the
matrix edge of phy are used as names.
an object of class "phylo".
