computeFbrp() Computes biological reference points corresponding to the proxy Fbrp

Description

computeFbrp() Computes biological reference points corresponding to the proxy Fbrp

Usage

computeFbrp(
  stock,
  sr = "missing",
  proxy = NULL,
  x = NULL,
  blim = 0.1,
  type = c("b0", "btgt", "value"),
  btri = "missing",
  bpa = "missing",
  bthresh = "missing",
  verbose = T,
  fmax = 10,
  ...
)

Arguments

stock	object of class FLStock
sr	stock recruitment model of class FLSR
proxy	choice of Fmsy proxies (combinations permitted) "sprx" spawning potential ratio spr/spr0 with basis x "bx" SSB as fraction xSSB0 "f0.1" 10 "fe40" Patterns estimator for Fmsy "msy" maximum surplus production (not defined for segreg) numeric user value
x	basis in percent for sprx and bx, e.g. 40 for spr40
blim	values < 1 are taken as fraction to B0 and blim > 1 as absolute values unless specified otherwise
type	type of blim input, values < 1 are "b0" fraction to B0 "btgt" fraction to Btarget (first occurring in proxy) "value" absolute value
btri	Btrigger can specified as absolute value
bpa	Bpa can specified as absolute value
bthresh	Bthresh (GFCM) interchangeable use with Bpa
verbose
fmax	maximum Flim = max(Flim,fmax*Fbrp)

Value

brp object of class FLBRP with computed Fbrp reference points

Examples

data(ple4)
srr = srrTMB(as.FLSR(ple4,model=rickerSV),spr0=spr0y(ple4))
brp = computeFbrp(stock=ple4,sr=srr,proxy=c("sprx","f0.1"),blim=0.1,type="b0")
ploteq(brp,obs=TRUE,refpts="msy")
