##### Usage
balance(phy)
##### Arguments
phy
an object of class "phylo".
##### Value

• a numeric matrix with two columns and one row for each node of the tree. The columns give the numbers of descendants on each daughter-branches (the order of both columns being arbitrary). If the phylogeny phy has an element node.label, this is used as rownames for the returned matrix; otherwise the numbers (of mode character) of the matrix edge of phy are used as rownames.
