Plankton encounter contribution

Computes the extra encounter rate that fish experience by feeding on the plankton component. This function is registered as the encounter_fun of the "plankton" component in newExtensionTemplateParams() and is called automatically by mizer::getEncounter() at each time step.

Usage

planktonEncounter(params, n, n_pp, n_other, component, ...)

Arguments

params

A MizerParams object.

n

Species abundance matrix (species × size).

n_pp

Resource abundance vector (full size grid).

n_other

Named list of other component states, including the current plankton spectrum under n_other[["plankton"]].

component

Name of this component ("plankton").

...

Additional arguments (ignored).

Value

A numeric matrix (species × size) of extra encounter rates due to plankton.

Details

The implementation is taken directly from the detritus example in vignette("extending-mizer", package = "mizer"). It treats the plankton spectrum as the resource (n_pp) in a standard mizer encounter calculation, after first removing the plankton's own encounter hook from the temporary params copy to avoid double-counting.
