Calculate the total biomass of each species within a size range at each time step.

Calculates the total biomass 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 length range 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).

getBiomass(sim, ...)

Arguments

sim	An object of class MizerSim.
...	Arguments passed on to get_size_range_array min_w Smallest weight in size range. Defaults to smallest weight in the model. max_w Largest weight in size range. Defaults to largest weight in the model. min_l Smallest length in size range. If supplied, this takes precedence over min_w. max_l Largest length in size range. If supplied, this takes precedence over max_w.

Value

An array containing the biomass (time x species)

Examples

if (FALSE) {
data(NS_species_params_gears)
data(inter)
params <- newMultispeciesParams(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)
getBiomass(sim)
getBiomass(sim, min_w = 10, max_w = 1000)
