Majority-rule consensus tree

Majority() is a simple alias of TreeTools::Consensus(), which computes the majority-rule consensus: the tree that contains each split that occurs in more than p of the input trees (Margush and McMorris 1981) .

Usage

Majority(trees, p = 0.5)

MajorityRule(trees, p = 0.5)

MR(trees, p = 0.5)

Arguments

trees

A list of trees, or a multiPhylo object. All entries must share the same leaf labels.

p

Numeric between 0.5 and 1: the minimum proportion of trees that must contain a split for it to be retained.

Value

Majority() returns an object of class phylo denoting the majority rule consensus, rooted as in the first entry of trees.
