R Documentation

Collapse branches of zero length to polytomy in stochastic map style tree

Description

This function collapses branches of zero length (or, more specifically, branches with length shorter than tol) to create a polytomy in a stochastic-map style tree.

Usage

di2multi.simmap(tree, tol=1e-08)

Arguments

`tree`	modified object of class `"phylo"` containing a stochastically mapped discrete character.
`tol`	length below which edges should be treated as having zero length.

Details

This function should theoretically perform similarly to di2multi in ape.

Value

A tree with a stochastically mapped discrete character
