Leaf label interchange
Description
LeafLabelInterchange() exchanges the position of leaves within a tree.
Usage
LeafLabelInterchange(tree, n = 2L)
Arguments
tree |
A tree of class |
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.
