![[Experimental]](figures/lifecycle-experimental.svg)
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().
Arguments
- object
An object of class MizerSim or MizerParams.
- 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.
- 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 four variables 'Predator', 'w', 'Proportion', 'Prey' is
returned.
Details
Prey species that contribute less than 1 permille to the diet are suppressed in the plot.
If more than one predator species is selected, then the plot contains one facet for each species.
