is_convergent_within: Evaluate within-habitat convergence stability

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

Evaluate within-habitat convergence stability

Description

Assesses whether an equilibrium trait value is convergent-stable, or attainable.

Usage

is_convergent_within(xeq, pars, step = 1e-04)

Arguments

xeq	Some equilibrium trait value
pars	An unevaluated parameter-list (e.g. as returned by get_default_pars)
step	How far from xeq the selection gradient should be computed

Details

This functions computes the selection gradient on both sides of the equilibrium xeq and looks at the sign of the difference between the two. If the selection gradient goes down at xeq the equilibrium is convergent, otherwise it is divergent.

Value

A boolean
