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