get_global_max_area_time: Get the time of maximum area

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

Description

Get the time of maximum area

Usage

get_global_max_area_time(totaltime, area_pars, island_ontogeny, sea_level)

Arguments

totaltime	stub
area_pars	a named list containing area and sea level parameters as created by create_area_pars: [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 [5]: amplitude of area fluctuation from sea level [6]: frequency of sine wave of area change from sea level
island_ontogeny	a numeric describing the type of island ontogeny. Can be NULL, 1 for a beta function describing area through time.
sea_level	stub

Value

Numeric with time at which area is maximum during the simulation.
