LeafLabelInterchange: Leaf label interchange

In TreeTools: Create, Modify and Analyse Phylogenetic Trees

Leaf label interchange

Description

LeafLabelInterchange() exchanges the position of leaves within a tree.

Usage

LeafLabelInterchange(tree, n = 2L)

Arguments

tree	A tree of class phylo.
n	Integer specifying number of leaves whose positions should be exchanged.

Details

Modifies a tree by switching the positions of n leaves. To avoid later swaps undoing earlier exchanges, all n leaves are guaranteed to change position. Note, however, that no attempt is made to avoid swapping equivalent leaves, for example, a pair that are each others' closest relatives. As such, the relationships within a tree are not guaranteed to be changed.

Value

LeafLabelInterchange() returns a tree of class phylo on which the position of n leaves have been exchanged. The tree's internal topology will not change.
