The recommended way to change the resource dynamics parameters is to use
setResource(). The resource_params list contains values that are helpful
in setting up the actual size-dependent parameters with setResource(). If
you have specified a custom resource dynamics function that requires
additional parameters, then these should also be added to the
resource_params list.
Details
The resource_params list will at least contain the slots kappa, lambda,
w_pp_cutoff and n.
The resource parameter n is the exponent for the power-law form for the
replenishment rate \(r_R(w)\): $$r_R(w) = r_R\, w^{n-1}.$$
The resource parameter lambda (\(\lambda\)) is the exponent for the
power-law form for the carrying capacity \(c_R(w)\) and w_pp_cutoff is
its cutoff value: $$c_R(w) = c_R w^{-\lambda}$$ for all \(w\) less than
w_pp_cutoff and zero for larger sizes.
The resource parameter kappa (\(\kappa\)) determines the initial resource
abundance: $$N_R(w) = \kappa\, w^{-\lambda}$$ for all \(w\) less than w_pp_cutoff and zero for larger
sizes.
