After running a projection, the total yield of each species by fishing gear can be plotted against time.

plotYieldGear(
  sim,
  species = NULL,
  total = FALSE,
  highlight = NULL,
  return_data = FALSE,
  ...
)

plotlyYieldGear(sim, species = NULL, total = FALSE, highlight = NULL, ...)

Arguments

sim

An object of class 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.

total

A boolean value that determines whether the total over all species in the system is plotted as well. Note that even if the plot only shows a selection of species, the total is including all species. Default is FALSE.

highlight

Name or vector of names of the species to be highlighted.

return_data

A boolean value that determines whether the formatted data used for the plot is returned instead of the plot itself. Default value is FALSE

...

Other arguments (currently unused)

Value

A ggplot2 object, unless return_data = TRUE, in which case a data frame with the four variables 'Year', 'Yield', 'Species' and 'Gear' is returned.

Details

This plot is pretty easy to do by hand. It just gets the biomass using the getYieldGear() method and plots using the ggplot2 package. You can then fiddle about with colours and linetypes etc. Just look at the source code for details.

sim <- project(params, effort=1, t_max=20, t_save = 0.2, progress_bar = FALSE)

plotYieldGear(sim, species = c("Cod", "Herring"), total = TRUE)
