create_yr_semester_age_length_key: Creates Age length key

In NOAA-EDAB/neusCatch: Multispecies length expansion of commercial catch

Creates Age length key

Description

Uses Gerritsen et al (2006) method for predicting missing values in age length key. Currently disregards gear type and only uses QTR/SEMESETER/YEAR.

Usage

create_yr_semester_age_length_key(
  expandedLandings,
  ageLengthData,
  filterYrs,
  plusAge,
  referenceAge,
  printConvergence = F
)

Arguments

expandedLandings	Data frame. Landings expanded by length distribution
ageLengthData	Data frame. Age-length data from databases
filterYrs	Numeric scalar. The First year in which age length key is required
plusAge	Numeric scalar. Maximum age category. (eg , 10+)
referenceAge	Numeric scalar.Used in the GLM as the age against which all the other ages are estimated. It is typically the most abundant age.
printConvergence	Boolean. Should convergence messages from multinom be printed to console (Default = F)
