Tabulate Stock-Recruitment Parameters

Tabulate Stock-Recruitment Parameters

ypr_tabulate_sr(object, ...)

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

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

Arguments

object

The population or populations.

...

Unused parameters.

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.
