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

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

# S3 method for class 'mizerMR'
plotDiet(
  object,
  species = NULL,
  time_range,
  wlim = c(1, NA),
  return_data = FALSE,
  ...
)

# S3 method for class 'mizerMRSim'
plotDiet(
  object,
  species = NULL,
  time_range,
  wlim = c(1, NA),
  return_data = FALSE,
  ...
)

plotDietMR(object, ...)

Arguments

object

An object of class MizerSim or MizerParams.

species

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

time_range

The time range (either a vector of values, a vector of min and max time, or a single value) to average the abundances over. Default is the final time step. Ignored when called with a MizerParams object.

wlim

A numeric vector of length two providing lower and upper limits for the w axis. Use NA to refer to the existing minimum or maximum.

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 three variables 'w', 'Proportion', 'Prey' is returned.

Details

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