DAISIE_calc_clade_imm_rate: Calculate the clade-wide immigration rate.

In xieshu95/Test-Trasie: Dynamical Assembly of Islands by Speciation, Immigration and Extinction

Description

Calculate the clade-wide immigration rate.

Usage

DAISIE_calc_clade_imm_rate(ps_imm_rate, n_island_species,
  n_mainland_species, carr_cap)

Arguments

ps_imm_rate	per species immigration rate
n_island_species	number of species in that clade on the island
n_mainland_species	number of species in that clade on the mainland
carr_cap	carrying capacity, number of species this clade will grow to

Value

the clade's immigration rate, which is at least zero. This rate will be zero if there are more species than the carrying capacity allows for
