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
