collapseUnsupportedEdges: Collapse Unsupported Edges

Description

Given a set of node support values (e.g., bootstrap proportions, posterior probabilities) and a certain threshold, all edges receiving less support than the threshold will be collapsed.

Usage

collapseUnsupportedEdges(phy, value, cutoff)

Arguments

phy

An object of class phylo.

value

A character string giving the name of the list element that contains the support values; default is "node.label"

cutoff

A numeric value giving the threshold below which edges will be collapsed.

Value

An object of class phylo.
