CatchCutoffMatrix: Create Annual (or Sampling Year) Length Cutoff Matrix.

In jasondubois/sportfish: Methods and Function for CDFW Sportfish Unit Data

Description

Because we cannot easily age sturgeon, length acts as a surrogate. Here, given min length and max length (usually from annual extant regulations) and VBGM, we calculate corresponding min age & max age. These ages then in turn are used to create length cutoff matrices.

Usage

CatchCutoffMatrix(relYear, minLen, maxLen, vb)

Arguments

relYear	Numeric. Release (tagging) or sampling 4-digit year.
minLen	Numeric. Minimum length, typically per regulations in place during 'relYear'.
maxLen	Numeric. Maximum length, typically per regulations in place during 'relYear'.
vb	Function. Output of GetVBGM().

Value

Matrix with five columns (RelYear, MinLen, MaxLen, MinAge, MaxAge), where MinAge & MaxAge calculated using length inputs & 'vb' function.
