globalMsy: hcrICES

In laurieKell/FLCandy: Candidate methods for FLR

hcrICES

Description

Calculates the global MSY, i.e. the largest catch that can be made with a knife edge selection pattern

Harvest Control Rule, calculates Total Allowable Catch (TAC) based on a hockey stock harvest control rule.

Usage

hcrICES(object,eql,sr_deviances,params, 
         start=max(dimnames(object)$year)-10, end=start+10, interval=1,
         err=NULL,bndTac=c(0,Inf),...)

Arguments

object	an object of class FLStock
eql	FLBRP with a stock recruitment relationship used for projection
...	any additional arguments
sr_deviances	FLQuant recuitment deviates on the log scale, i.e. multiplicative
params	FLPar HCR parameters, specifying blim, btrig, bmin, ftar and fmin
start	numeric first year for simulation
end	numeric last year for simulation
interval	numeric time step, 1 year by default
err	FLQuant assessment error on SSB for year used for HCR
bndTac	numeric bounds on TAC, by default these are turned off, for 20 percent constraint set to c(0.8,1.2)

Value

returns a list with FLStock and FLPar objects for the stock and HCR
