[Experimental] Plots the proportions with which each prey species contributes to the total biomass consumed by the specified predator species, as a function of the predator's size. These proportions are obtained with getDiet().

plotDiet(object, species = NULL, return_data = FALSE)

Arguments

object

An object of class MizerSim or MizerParams.

species

The name of the predator species for which to plot the diet.

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

Value

A ggplot2 object, unless return_data = TRUE, in which case a data frame with the three variables 'w', 'Proportion', 'Prey' is returned.

Details

Prey species that contribute less than 1 permille to the diet are suppressed in the plot.
