ypr_plot_yield: Plot Yield by Capture

In ypr: Yield Per Recruit

Plot Yield by Capture

Description

Plots the 'Yield', 'Age', 'Length', 'Weight', 'Effort', or 'YPUE' by the annual interval capture/exploitation probability.

Usage

ypr_plot_yield(object, ...)

## Default S3 method:
ypr_plot_yield(
  object,
  y = "Yield",
  pi = seq(0, 1, length.out = 100),
  Ly = 0,
  harvest = TRUE,
  biomass = FALSE,
  u = harvest,
  plot_values = TRUE,
  ...
)

## S3 method for class 'ypr_populations'
ypr_plot_yield(
  object,
  y = "Yield",
  pi = seq(0, 1, length.out = 100),
  Ly = 0,
  harvest = TRUE,
  biomass = FALSE,
  u = harvest,
  plot_values = TRUE,
  ...
)

Arguments

object	The population or populations.
...	Unused parameters.
y	A string of the term on the y-axis.
pi	A vector of probabilities of capture to calculate the yield for.
Ly	The minimum length (trophy) fish to consider when calculating the yield (cm).
harvest	A flag specifying whether to calculate the yield for harvested fish or captures.
biomass	A flag specifying whether to calculate the yield in terms of the biomass versus number of individuals.
u	A flag specifying whether to plot the exploitation rate as opposed to the capture rate.
plot_values	A flag specifying whether to plot the actual and optimal values.

Value

A ggplot2 object.
