Resource parameters
Description
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.
Usage
resource_params(params)
resource_params(params) <- value
Arguments
params |
A MizerParams object |
value |
A named list of resource parameters. |
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.
Value
A named list of resource parameters.
