getRDI: getRDI method for the size based model

In pwoodworth-jefcoats/Size-Based-Modeling: Mizer With The Effects Of Temperature Included

getRDI method for the size based model

Description

Calculates the density independent recruitment (total egg production) R_{p,i} before density dependence, by species. Used by the project_therMizer method for performing simulations.

getRDI method with e_spawning argument.

Usage

getRDI(object, n, n_pp, e_spawning, ...)

## S4 method for signature 'therMizerParams,matrix,numeric,matrix'
getRDI(object, n, n_pp,
  e_spawning, sex_ratio = 0.5)

Arguments

object	A therMizerParams 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.
...	Other arguments (currently unused).
sex_ratio	Proportion of the population that is female. Default value is 0.5.
ocean_temp	A numeric vector of the ocean temperature by realm or a single numeric ocean_temp value which is used for all realms.

Value

A numeric vector the length of the number of species

Examples

## Not run: 
data(NS_species_params_gears)
data(inter)
params <- therMizerParams(NS_species_params_gears, inter)
# Project with constant fishing effort for all gears for 20 time steps
sim <- project_therMizer(params, t_max = 20, effort = 0.5)
# Get the recruitment at a particular time step
getRDI(params,sim@n[21,,],sim@n_pp[21,])

## End(Not run)
