Values used as starting values for simulations with project().

initialN(params) <- value

initialN(object)

Arguments

params

A MizerParams object

value

A matrix with dimensions species x size holding the initial number densities for the fish spectra.

object

An object of class MizerParams or MizerSim

Examples

# Doubling abundance of Cod in the initial state of the North Sea model params <- NS_params initialN(params)["Cod", ] <- 2 * initialN(params)["Cod", ] # Calculating the corresponding initial biomass biomass <- initialN(params)["Cod", ] * dw(NS_params) * w(NS_params) # Of course this initial state will no longer be a steady state params <- steady(params)
#> Convergence was achieved in 19.5 years.
#> Warning: The following species require an unrealistic reproductive efficiency greater than 1: Sprat, Sandeel, Cod, Saithe
