mizer (version 1.0.1)

getN: Calculate the total abundance in terms of numbers of species within a size range

Description

Calculates the total numbers through time of the species in the MizerSim class within user defined size limits. The default option is to use the whole size range You can specify minimum and maximum weight or lengths for the species. Lengths take precedence over weights (i.e. if both min_l and min_w are supplied, only min_l will be used)

Usage

getN(object, ...)
# S4 method for MizerSim
getN(object, ...)

Arguments

object

An object of class MizerSim.

...

Other arguments to select the size range of the species to be used in the calculation (min_w, max_w, min_l, max_l).

Value

An array containing the total numbers (time x species)

Examples

# NOT RUN {
data(NS_species_params_gears)
data(inter)
params <- MizerParams(NS_species_params_gears, inter)
# With constant fishing effort for all gears for 20 time steps
sim <- project(params, t_max = 20, effort = 0.5)
getN(sim)
getN(sim, min_w = 10, max_w = 1000)
# }
