sim_sgd: Algorithm for simulating a phylogenetic tree under the SGD model

Description

Simulates a phylogeny arising from the SGD model with exponentially increasing metapopulation size. Notations follow Manceau et al. (2015).

Usage

sim_sgd(tau, b, d, nu)

Arguments

tau

the simulation time, which corresponds to the length of the phylogeny

b

the (constant) per-individual birth rate

d

the (constant) per-individual death rate

nu

the (constant) per-individual mutation rate

Value

a phylogenetic tree of class "phylo" (see ape documentation)

Examples

tau <- 10
b <- 1e6
d <- b-0.5
nu <- 0.6
tree <- sim_sgd(tau,b,d,nu)
