ReportRecaCatchAtLengthAndAge: Report catch at length and age

In StoXProject/RstoxFDA: Fisheries Dependent Analysis with RstoX

Report catch at length and age

Description

Tabulates summary statistics for total catch (number) at all age-length combinations from MCMC simulations using Reca. MCMC simulations are typically obtained with RunRecaModels. Summary statistics are obtained from the posterior distribution, and the interval is reported as equal-tailed credible intervals.

Different length groups than the ones reported in the argument 'RecaCatchAtAge' may be specified with the argument 'IntervalWidth'. This will specify equi-intervalled lengthgroups with the smallest lengthgroup starting at 0. If it does not align with the length groups reported in 'RecaCatchAtAge' length group assignment is done to the highest overlapping length group.

If 'RecaCatchAtAge' contains estimate for a set of aggregation variables, such as area, gear, stock, etc., summary statistics will be presented similarly.

Rounding of numbers according to the argument 'Decimals' is done with round, so that negative numbers specify rounding to powers of ten, and rounding of the digit 5 is towards the even digit.

The units considered valid for catch at length in numbers are those listed for quantity 'cardinaltiy' in StoxUnits

Usage

ReportRecaCatchAtLengthAndAge(
  RecaCatchAtAge,
  PlusGroup = integer(),
  LengthInterval = numeric(),
  IntervalWidth = numeric(),
  Decimals = integer(),
  Unit = RstoxData::getUnitOptions("cardinality", conversionRange = c(1, 1e+12))
)

Arguments

RecaCatchAtAge	Results from MCMC simulations (RecaCatchAtAge).
PlusGroup	If given, ages 'PlusGroup' or older are included in a plus group.
LengthInterval	width of length bins in cm. If not provided, the interval in 'RecaCatchAtAge' will be used.
IntervalWidth	The width of the reported credible interval. A value of 0.9 gives 90 per cent credible intervals. Defaults to 0.9
Decimals	integer specifying the number of decimals to report for 'CatchAtAge', 'SD', 'Low' and 'High'. Defaults to 0.
Unit	unit for 'CatchAtAge', 'SD', 'Low' and 'High'
