extract_endemic_clade {DAISIEprep}

Extracts the information for an endemic clade (i.e. more than one species on the island more closely related to each other than other mainland species) from a phylogeny (specifically phylo4d object from phylobase package) and stores it in an Island_colonist class

Description

Extracts the information for an endemic clade (i.e. more than one species on the island more closely related to each other than other mainland species) from a phylogeny (specifically phylo4d object from phylobase package) and stores it in an Island_colonist class

Usage

extract_endemic_clade(phylod, species_label, unique_clade_name)

Arguments

phylod

A phylo4d object from the package phylobase containing phylogenetic and endemicity data for each species.

species_label

The tip label of the species of interest.

unique_clade_name

Boolean determining whether a unique species identifier is used as the clade name in the Island_tbl object or a genus name which may not be unique if that genus has several independent island colonisations

Value

An object of Island_colonist class
