markBackground: Designate species as background species

In mizer: Dynamic Multi-Species Size Spectrum Modelling

Designate species as background species

Description

Marks the specified set of species as background species by setting the is_background column in their species parameters to TRUE. Background species are handled differently in plots (displayed in grey) and their abundances can be automatically adjusted to keep the community close to the Sheldon spectrum (see adjustBackgroundSpecies() in the mizerExperimental package).

Usage

markBackground(object, species = NULL)

Arguments

object	An object of class MizerParams or MizerSim.
species	The species to be selected. Optional. By default all target species are selected. 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 selected (TRUE) or not.

Value

An object of the same class as the object argument

Examples

params <- markBackground(NS_params,
                         species = c("Sprat", "Sandeel", "N.pout"))
any(species_params(params)$is_background)
