Alias for getERepro()

An alias provided for backward compatibility with mizer version <= 1.0

getESpawning(
  params,
  n = initialN(params),
  n_pp = initialNResource(params),
  n_other = initialNOther(params),
  t = 0,
  ...
)

Arguments

params	A MizerParams object
n	A matrix of species abundances (species x size).
n_pp	A vector of the resource abundance by size
n_other	A list of abundances for other dynamical components of the ecosystem
t	The time for which to do the calculation (Not used by standard mizer rate functions but useful for extensions with time-dependent parameters.)
...	Unused

Value

A two dimensional array (prey species x prey size) holding $$\psi_i(w)E_{r.i}(w)$$ where \(E_{r.i}(w)\) is the rate at which energy becomes available for growth and reproduction, calculated with getEReproAndGrowth(), and \(\psi_i(w)\) is the proportion of this energy that is used for reproduction. This proportion is taken from the params object and is set with setReproduction().

Your own reproduction rate function

By default getERepro() calls mizerERepro(). However you can replace this with your own alternative reproduction rate function. If your function is called "myERepro" then you register it in a MizerParams object params with

params <- setRateFunction(params, "ERepro", "myERepro")

Your function will then be called instead of mizerERepro(), with the same arguments.

Examples

if (FALSE) {
params <- NS_params
# Project with constant fishing effort for all gears for 20 time steps
sim <- project(params, t_max = 20, effort = 0.5)
# Get the energy at a particular time step
getERepro(params, n = N(sim)[15, , ], n_pp = NResource(sim)[15, ], t = 15)
}
