Calculates the potential rate (in units 1/year) at which a prey individual of
a given size \(w\) is killed by predators from species \(j\). In formulas
$${\tt pred\_rate}_j(w_p) = \int \phi_j(w,w_p) (1-f_j(w))
\gamma_j(w) N_j(w) \, dw.$$
This potential rate is used in the function mizerPredMort() to
calculate the realised predation mortality rate on the prey individual.
mizerPredRate(params, n, n_pp, n_other, feeding_level, ...)A matrix of species abundances (species x size).
A vector of the resource abundance by size
A list of abundances for other dynamical components of the ecosystem
The current feeding level (optional). A matrix of size
no. species x no. size bins. If not supplied, is calculated internally
using the getFeedingLevel() function.
Unused
A two dimensional array (predator species x prey size) with the predation rate, where the prey size runs over fish community plus resource spectrum.
