random_tree: Create a random ranked phylogeny

In rrnni: Manipulate with RNNI Tree Space

Create a random ranked phylogeny

Description

Create a random ranked phylogeny using the coalescent method.

Usage

random_tree(n)

Arguments

n	the number of tips

Details

This is implementation of a ranked coalescent algorithm described in Collienne (2021). Starting from n tips of a tree, all with rank 0, randomly select two tips and merge them into a new node with rank 1, and add the new node to remaining tips. In next iteration, assign rank 2 and so on, until only a single node, the root, remains.

Value

random ranked tree of class "rankedPhylo"
