Get predation mortality rate for resource needed to project standard mizer model
Source:R/project_methods.R
mizerResourceMort.Rd
Calculates the predation mortality rate \(\mu_p(w)\) on the resource
spectrum by resource size (in units 1/year).
You would not usually call this
function directly but instead use getResourceMort()
, which then calls this
function unless an alternative function has been registered, see below.
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.)
- pred_rate
A two dimensional array (predator species x prey size) with the predation rate, where the prey size runs over fish community plus resource spectrum.

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