TreesMatchingTree: Number of trees containing a tree

Description

TreesMatchingTree() calculates the number of unrooted binary trees that are consistent with a tree topology on the same leaves.

Usage

TreesMatchingTree(tree)
LnTreesMatchingTree(tree)
Log2TreesMatchingTree(tree)

Arguments

tree

A tree of class phylo.

Value

TreesMatchingTree() returns a numeric specifying the number of unrooted binary trees that contain all the edges present in the input tree.

LnTreesMatchingTree() gives the natural logarithm of this number.
