Apply the sweep of different gear (and cruise) — GearDependentSpeciesCategoryCatchCompensation • RstoxBase

This function multiplies the CatchFractionWeight and CatchFractionNumber of a SpeciesCategoryCatchData by the sweep width given by CompensationTable. The result is a sweep width compensated length distribution (SpeciesCategoryCatchType starting with "SweepWidthCompensated").

GearDependentSpeciesCategoryCatchCompensation(
  SpeciesCategoryCatchData,
  CompensationMethod = c("Gear", "Cruise", "GearAndCruise"),
  CompensationTable = data.table::data.table()
)

Arguments

SpeciesCategoryCatchData: The SpeciesCategoryCatchData data.
CompensationMethod: The method to use for the length dependent catch compensation, i.e. specifying which columns to provide the sweep width for.
CompensationTable: A table of the sweep width per combination of the variables specified in CompensationMethod. Note that all combinations present in the data must be given in the table, as the output should be sweep width compensated for all rows with non-missing WeightedNumber.

Value

A SpeciesCategoryCatchData object.
