getRDI method for the size based model

Share:

Description

Calculates the density independent recruitment (total egg production) before density dependence, by species. Used by the project method for performing simulations.

Arguments

object

A MizerParams object.

n

A matrix of species abundance (species x size).

n_pp

A vector of the background abundance by size.

e_spawning

The energy available for spawning (optional). A matrix of size no. species x no. size bins. If not supplied, is calculated internally using the getESpawning() method.

sex_ratio

Proportion of the population that is female. Default value is 0.5.

Value

A numeric vector the length of the number of species
