In duplisea/ccca: Climate Change Conditioned Advice for Sustainable Fisheries Exploitation

Description

Determine the annual P/B of the population. Write input file with P/B column

Usage

PB.f(dataset, ref.years, q)

Arguments

dataset	the dataframe with at least the columns named "Year", "Catch", "Index", "E". There cannot be missing years but the code does not check for that - beware!
ref.years	the years which are considered the reference point year (e.g. for B, E, catch). It is up to you think it is representative of Blim, Bmsy, Busr or whatever. Just beware that reference point multipliers will be based on it in other areas of the simulation. So if it is a Bmsy proxy then the Blim ref.pt input logically might be about 0.4.
q	the survey catchability

Examples

PB= PB.f(dataset,1)
