[Deprecated]

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.

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)
