In mizer: Dynamic Multi-Species Size Spectrum Modelling

Get available energy

Description

This is deprecated and is no longer used by the mizer project() method. Calculates the amount E_{a,i}(w) of food exposed to each predator as a function of predator size.

Usage

getPhiPrey(object, n, n_pp, ...)

Arguments

object	An MizerParams object
n	A matrix of species abundances (species x size)
n_pp	A vector of the background abundance by size
...	Other arguments (currently unused)

Value

A two dimensional array (predator species x predator size)

Examples

params <-  NS_params
sim <- project(params, t_max = 20, effort = 0.5)
n <- sim@n[21,,]
n_pp <- sim@n_pp[21,]
getPhiPrey(params,n,n_pp)
# ->
getEncounter(params) / getSearchVolume(params)
