mizer (version 3.0.0)

plot_diet: Build the diet-composition plot

Description

Internal worker shared by the plotDiet() methods. It melts the diet array into a data frame, restricts to meaningful size ranges, converts to a length axis if requested and draws a stacked-area plot of prey proportions.

Usage

plot_diet(
  params,
  n,
  diet,
  species,
  log_x,
  log_y,
  wlim,
  llim,
  size_axis,
  return_data
)

Value

A mizer_plot (ggplot2) object, or the plotting data frame if return_data = TRUE.

Arguments

params

A MizerParams object.

n

Array of species abundances (species by size).

diet

Array of diet proportions (predator by size by prey).

species

The predator species to be plotted.

log_x, log_y

Logical flags for log10 axes.

wlim, llim

Numeric vectors of length two giving the weight and length limits.

size_axis

Either "w" (weight) or "l" (length).

return_data

If TRUE, return the plotting data frame instead of the plot.
