polyBalance: Balance of a phylogenetic tree with polytomies
In boopsboops/spider: Species Identity and Evolution in R
polyBalance R Documentation
Balance of a phylogenetic tree with polytomies
Description
This function computes the numbers of descendants for each dichotomous
branch of a phylogenetic tree.
Usage
polyBalance(phy)
Arguments
phy
A tree of class ‘phylo’.
Details
The function extends balance to allow the balance of a tree
with polytomies to be calculated. When the tree is fully dichotomous, the
result is identical to balance.
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 node.
Non-dichotomous nodes are reported as 'NA'.

Examples
set.seed(55)
tr <- ape::rtree(15)
tr2 <- ape::di2multi(tr, tol=0.02)
polyBalance(tr)
polyBalance(tr2)
