get_immig_rate: Calculate immigration rate

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

Description

Internal function. Calculates the immigration rate given the current number of species in the system, the carrying capacity

Usage

get_immig_rate(timeval, totaltime, gam, Apars, Tpars = NULL,
  island_ontogeny, island_spec, K, mainland_n)

Arguments

timeval	current time of simulation
totaltime	total time of simulation
gam	per capita immigration rate
Apars	a named list containing area parameters as created by create_area_params: [1]: maximum area [2]: value from 0 to 1 indicating where in the island's history the peak area is achieved [3]: sharpness of peak [4]: total island age
Tpars	A named list containing diversification rates considering two trait states: [1]:A numeric with the per capita transition rate with state1 [2]:A numeric with the per capita immigration rate with state2 [3]:A numeric with the per capita extinction rate with state2 [4]:A numeric with the per capita anagenesis rate with state2 [5]:A numeric with the per capita cladogenesis rate with state2 [6]:A numeric with the per capita transition rate with state2 [7]:A numeric with the number of species with trait state 2 on mainland
island_ontogeny	a string describing the type of island ontogeny. Can be NULL, "beta" for a beta function describing area through time, or "linear" for a linear function
island_spec	matrix with current state of system
K	carrying capacity
mainland_n	total number of species present in the mainland
