This function matches the observed yields of all the gears for all the species by scaling the catchabilities by the ratio between current modelled yield and observed yield.
Usage
matchYield(
params,
species = NULL,
gears = NULL,
keep = c("egg", "biomass", "number")
)Arguments
- params
A MizerParams object
- species
The species to be affected. Optional. By default all observed biomasses will be matched. A vector of species names, or a numeric vector with the species indices, or a logical vector indicating for each species whether it is to be affected (TRUE) or not.
- gears
The gears to be affected. Optional. By default all gears will be affected. A vector of gear names.
- keep
A string determining which quantity is to be kept constant. The choices are "egg" which keeps the egg density constant, "biomass" which keeps the total biomass of the species constant and "number" which keeps the total number of individuals constant.
