get_t_hor: Function to calculate and update horizon for maximum...

In xieshu95/Trait_dependent_TraiSIE: Dynamical Assembly of Islands by Speciation, Immigration and Extinction

Description

Internal function. Calculates when the next horizon for maximum extinction will be in the simulation

Usage

get_t_hor(timeval, totaltime, Tpars, Apars, ext, ext_multiplier,
  island_ontogeny, t_hor)

Arguments

timeval	current time of simulation
totaltime	total time of simulation
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
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
ext	effective extinction rate at timeval
ext_multiplier	reduces or increases distance of horizon to current simulation time
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
t_hor	time of horizon for max extinction
