Tabulate Yields

ypr_tabulate_yields(object, ...)

# S3 method for default
ypr_tabulate_yields(
  object,
  pi = seq(0, 1, length.out = 100),
  Ly = 0,
  harvest = TRUE,
  biomass = FALSE,
  all = FALSE,
  ...
)

# S3 method for ypr_populations
ypr_tabulate_yields(
  object,
  pi = seq(0, 1, length.out = 100),
  Ly = 0,
  harvest = TRUE,
  biomass = FALSE,
  all = FALSE,
  ...
)

Arguments

object

The population or populations.

...

Unused parameters.

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.

all

A flag specifying whether to include all parameter values.

Value

A data frame.
