get_immig_rate: Calculate immigration rate

Description Usage Arguments Author(s) References See Also

View source: R/DAISIE_rates.R

Description

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

Usage

1
2
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 carrying capacity with trait state 2 on mainland

  • [8]: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
