Description

Calculates the area at a point in time from a beta function

Usage

1
calc_Abeta(proptime, proptime_max, peak, Amax)

Arguments

proptime

A numeric from 0 to 1. The proportion of time that has elapsed in the simulation, in relation to the total island age (NB: not the simulation time, but island age).

proptime_max

A numeric from 0 to 1. The same as proportional_peak_t. Indicates, in proportion to the total island age when the ontogeny peak should occur (i.e. 0.5 means a peak halfway in time).

peak

A numeric value specifying the peakiness (or shaprness) of the ontogeny curve. Higher values imply peakier ontogeny. This value is internally calculated by calc_peak() given the area at the present and the area_pars.

Amax

A numeric value for maximum island area during the simulation.

Value

Numeric
