In nikolaifish/bamExtras: Functions and Data in Support of Stock Assessments with the Beaufort Assessment Model (BAM)

Calculate proportion mature population from rdat. Either proportion female-at-age (for gonochoristic) or proportion combined proportion male and female maturity at age (for protogynous)

Description

Calculate proportion mature population from rdat. Either proportion female-at-age (for gonochoristic) or proportion combined proportion male and female maturity at age (for protogynous)

Usage

pmatage(a.series, Mat_age1_max = 0.49, herm = "gonochoristic", age = NULL)

Arguments

a.series	life history-at-age data with naming conventions used in BAM rdat$a.series data frames. Expects column "age", "mat.female", prop.female and looks for columns "mat.male".
Mat_age1_max	Limit maximum value of proportion mature of first age class (usually age-0 or age-1). Models sometimes fail when maturity of first age class is too high (e.g. >0.5)
herm	Is the species hermaphroditic? If "gonochoristic", use female maturity. If "protogynous", use a function of male and female maturity.
age	Vector of ages to include
