find_equilibrium_di: Find the dimorphic demographic equilibrium

In rscherrer/speciomx: Adaptive Dynamics Approximation of the Speciome Model

Find the dimorphic demographic equilibrium

Description

Solves the demographic equilibrium equation for the population sizes in the two morphs and the two habitats, after branching has occurred, given parameter values.

Usage

find_equilibrium_di(xres1, xres2, pars, init)

Arguments

xres1	The resident trait value in the first morph
xres2	The resident trait value in the second morph
pars	An unevaluated parameter-list (e.g. as returned by get_default_pars)
init	A vector of four starting values for solving of the demographic equilibrium

Details

This function uses a multivariate numerical root finding algorithm (?pracma::fsolve) to find solutions to the equation.

Value

A vector of four equilibrium population sizes: morph 1 in habitat 1, morph 1 in habitat 2, morph 2 in habitat 1 and morph 2 in habitat 2.

Examples

pars <- get_default_pars()
find_equilibrium_di(-0.001, 0.001, pars, init = rep(1000, 4))
