popdynOneTS: Population dynamics model for one annual time-step

Description

Project population forward one time-step given current numbers-at-age and total mortality

Usage

popdynOneTS(nareas, maxage, SSBcurr, Ncurr, Zcurr, PerrYr, hc, R0c, SSBpRc, aRc,
  bRc, movc, SRrelc)

Arguments

nareas

The number of spatial areas

maxage

The maximum age

SSBcurr

A numeric vector of length nareas with the current spawning biomass in each area

Ncurr

A numeric matrix (maxage, nareas) with current numbers-at-age in each area

Zcurr

A numeric matrix (maxage, nareas) with total mortality-at-age in each area

PerrYr

A numeric value with recruitment deviation for current year

R0c

Numeric vector with unfished recruitment by area

SSBpRc

Numeric vector with unfished spawning stock per recruit by area

aRc

Numeric vector with Ricker SRR a parameter by area

bRc

Numeric vector with Ricker SRR b parameter by area

movc

Numeric matrix (nareas by nareas) with the movement matrix

SRrelc

Integer indicating the stock-recruitment relationship to use (1 for Beverton-Holt, 2 for Ricker)

hs

Steepness of SRR
