In DDD: Diversity-Dependent Diversification

Function to convert a table with speciation and extinction events to a set of branching times

Description

Converting a table with speciation and extinction events to a set of branching times

Usage

L2brts(L, dropextinct = T)

Arguments

L

Matrix of events as produced by dd_sim: - the first column is the time at which a species is born in Mya - the second column is the label of the parent of the species; positive and negative values indicate whether the species belongs to the left or right crown lineage - the third column is the label of the daughter species itself; positive and negative values indicate whether the species belongs to the left or right crown lineage - the fourth column is the time of extinction of the species; if the fourth element equals -1, then the species is still extant.

dropextinct

Sets whether the phylogeny should drop species that are extinct at the present

Value

brts	A set of branching times
