Tabulate Stock-Recruitment Parameters

Tabulate Stock-Recruitment Parameters

Usage

ypr_tabulate_sr(object, ...)

# Default S3 method
ypr_tabulate_sr(
  object,
  Ly = 0,
  harvest = TRUE,
  biomass = FALSE,
  all = FALSE,
  ...
)

# S3 method for class 'ypr_populations'
ypr_tabulate_sr(
  object,
  Ly = 0,
  harvest = TRUE,
  biomass = FALSE,
  all = FALSE,
  ...
)

Arguments

object

The population or populations.

...

These dots are for future extensions and must be empty.

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 of stock-recruitment parameters.
