Report catch at length

Description

Tabulates summary statistics for analytical catch at length estimate. Summary statistics are obtained as analytical domain estimates, including a length-group domain, obtained by annotating sample data with the function AddLengthGroupStoxBiotic. An estimate of the standard deviation of their sampling distribution (the standard error) is also provided. Confidence intervals are calculated from a Gaussian approximation to the sampling distribution.

If AnalyticalPopulationEstimateData contains estimates for domains that include more than just length group, 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

ReportAnalyticalCatchAtLength(
  AnalyticalPopulationEstimateData,
  LengthGroupVariable = character(),
  IntervalWidth = numeric(),
  Decimals = integer(),
  Unit = RstoxData::getUnitOptions("cardinality", conversionRange = c(1, 1e+12))
)

Arguments

AnalyticalPopulationEstimateData	Results from analytical estimates (AnalyticalPopulationEstimateData). A variable identifying length groups (argument: 'LengthGroupVariable') must be among the domain variables. This must be formatted as done by AddLengthGroupStoxBiotic.
LengthGroupVariable	Name of domain variable in 'AnalyticalPopulationEstimateData' that identifies length group.
IntervalWidth	The width of the reported confidence interval. A value of 0.9 gives 90 per cent confidence intervals.
Decimals	integer specifying the number of decimals to report for 'CatchAtLength', 'SD', 'Low' and 'High'.
Unit	unit for 'CatchAtLength', 'SD', 'Low' and 'High'
