genPDATree: Generation of rooted binary trees under the PDA model
Description
genPDATree - Generates a rooted binary tree in phylo
format with the given number of n leaves under the
proportional-to-distinguishable-arrangements model.
Given n, all phylogenies (trees with labeled leaves) with
n leaves are equiprobable under the PDA.
Usage
genPDATree(n)
Value
genPDATree A single tree of class phylo is returned.
Arguments
n
Integer value that specifies the desired number of leaves, i.e.,
vertices with in-degree 1 and out-degree 0.
Due to the restrictions of the phylo or multiphylo format,
the number of leaves must be at least 2 since there must be at
least one edge.
