Project forward an FLStock for a fbar target

Projection of an FLStock object for a fishing mortality target does not always require the features of fwd().Fast-forward an FLStock object for a fishing mortality yearly target only.

ffwd(object, sr, fbar = control, control = fbar, deviances = "missing")

Arguments

object

An *FLStock*

sr

A stock-recruit relationship, *FLSR* or *predictModel*.

fbar

Yearly target for average fishing mortality, *FLQuant*.

control

Yearly target for average fishing mortality, *fwdControl*.

deviances

Deviances for the strock-recruit relationsip, *FLQuant*.

Value

The projected *FLStock* object.

Examples

data(ple4)
sr <- predictModel(model=bevholt, params=FLPar(a=140.4e4, b=1.448e5))
# Project for fixed Fbar=0.21
run <- ffwd(ple4, sr=sr, fbar=FLQuant(0.21, dimnames=list(year=1958:2017)))
plot(run)

# Same projection with fwd()
test <- fwd(ple4, sr=sr, fbar=FLQuant(0.21, dimnames=list(year=1958:2017)))
plot(run, test)
