Consensus {TreeTools}

Construct consensus trees

Description

Consensus() calculates the consensus of a set of trees, using the algorithm of (Day 1985).

Usage

Consensus(trees, p = 1, check.labels = TRUE)

Arguments

trees

List of trees, optionally of class multiPhylo.

p

Proportion of trees that must contain a split for it to be reported in the consensus. p = 0.5 gives the majority-rule consensus; p = 1 (the default) gives the strict consensus.

check.labels

Logical specifying whether to check that all trees have identical labels. Defaults to TRUE, which is slower.

Value

Consensus() returns an object of class phylo, rooted as in the first entry of trees.
