mizer (version 2.3.0)

plotDiet: Plot diet, resolved by prey species, as function of predator at size.

Description

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().

Usage

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.
