new_sID: Generate a new stock ID object

In smartell/CatchMSY: Catch-MSY method for estimating MSY-based reference points

Description

Generates a template sID object for new assessments.

Usage

new_sID(id = "Stock Label", age = 1:10, linf = 100, winf = 5,
  vbk = 0.2, to = 0, a = 5e-06, b = 3, ah = 2, gh = 0.2, m = 0.2,
  fmsy = 0.15, msy = 1, binwidth = 1, la.cv = 0.1, sigma_r = 0,
  smodel = "logistic", dfile = "")

Arguments

id	Name of Stock
age	A vector of integer ages where the terminal age is a plus group.
linf	Asymptotic length for von Bertalanffy growth
winf	Asymptotic weight.
vbk	von Bertalanffy growth coefficient.
to	theoretical age at 0 length (years).
a	allometric scaler in length-weight relationship w = a L ^b
b	allometric power parameter in length-weight relationship
ah	age at 50% maturity
gh	standard deviation in age at 50% maturity
m	natural mortality
fmsy	fishing mortality at maximum sustainable yield
msy	maximum sustainable yield
binwidth	bin width for length composition data
la.cv	coefficient of variation for length-at-age curve
sigma_r	standard deviation for recruitment variation
smodel	"logistic" to specify logistic selectivity curve, "dome" to specify dome-shaped selectivity curve
dfile	Name of file containing time series data

Details

This function returns a list object containing all the necessary information to run the catchMSY routines. Column headings are: year catch biomass biomass.lse index index.lse

Value

A template for a stock class object.

Examples

myStock <- new_sID()
names(myStock)
