Marks the specified set of species as background species. Background species are handled differently in some plots and their abundance is automatically adjusted in adjustBackgroundSpecies() to keep the community close to the Sheldon spectrum.

markBackground(object, species = NULL)

## Arguments

object An object of class MizerParams or MizerSim. 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

if (FALSE) {
params <- newMultispeciesParams(NS_species_params_gears, inter)
sim <- project(params, effort=1, t_max=20, t_save = 0.2, progress_bar = FALSE)
sim <- markBackground(sim, species = c("Sprat", "Sandeel",
"N.pout", "Dab", "Saithe"))
plotSpectra(sim)
}
