getM2Background: Alias for 'getResourceMort()'

In mizer: Dynamic Multi-Species Size Spectrum Modelling

Alias for getResourceMort()

Description

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

Usage

getM2Background(
  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 vector of mortality rate by resource size.

Your own resource mortality function

By default getResourceMort() calls mizerResourceMort(). However you can replace this with your own alternative resource mortality function. If your function is called "myResourceMort" then you register it in a MizerParams object params with

params <- setRateFunction(params, "ResourceMort", "myResourceMort")

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

Other rate functions: getEGrowth(), getERepro(), getEReproAndGrowth(), getEncounter(), getFMort(), getFMortGear(), getFeedingLevel(), getMort(), getPredMort(), getPredRate(), getRDD(), getRDI(), getRates()

Examples

params <- NS_params
# With constant fishing effort for all gears for 20 time steps
sim <- project(params, t_max = 20, effort = 0.5)
# Get resource mortality at one time step
getResourceMort(params, n = N(sim)[15, , ], n_pp = NResource(sim)[15, ])
