plotWKREF Plots the new proposed ICES advice rule

Description

plotWKREF Plots the new proposed ICES advice rule

Usage

plotWKREF(
  ftgt = 1,
  btgt = 1,
  blim = 0.2,
  btrigger = 0.9 * btgt,
  bthresh = 0.8 * btgt,
  bclose = 0,
  fmin = 0,
  obs = "missing",
  kobe = TRUE,
  alpha = 1,
  xmax = 1.3,
  ymax = 1.5,
  ylab = "missing",
  xlab = "missing",
  rel = FALSE,
  expand = TRUE,
  labels = TRUE,
  critical = kobe
)

Arguments

ftgt	Target F = min(Fbrp,Fp0.5)
btgt	Biomass target corresponding to Fbrp
blim	biomass limit
btrigger	biomass trigger below which F is linearly reduced
bthresh	biomass threshold beyond which biomass is classified sustainable
bclose	ratio biomass/blim that invokes fishing closure relative to blim
fmin	minimum allowable (bycatch) fishing mortality under closure
obs	obtion to show observation with input class 'FLStock'
kobe	add kobe colour-coding
alpha	transparency of shading
xmax	multiplier for upper default xlim
ymax	multiplier for upper default ylim
ylab	option customize ylab
xlab	option customize xlab
rel	option to denote x,y labs as relative B/Btgt and F/Ftgt
expand	option to expand the plot area to border - default TRUE
labels	annotate reference point labels
critical	option to highlight critical zone below blim

Value

ggplot

Examples

plotWKREF()
# Close fishery at Blim and adjust axis labels to relative
plotWKREF(blim=0.2,bclose=0.2,rel=TRUE)
# Close fishery at Blim, but allow fmin (e.g. bycatch)
plotWKREF(blim=0.2,bclose=0.2,fmin=0.1,rel=TRUE)
# Change Btrigger above Btgt
plotWKREF(blim=0.2,bclose=0.2,fmin=0.1,btrigger=0.80,rel=TRUE)
# Plot stock data
data(ple4)
plotWKREF(ftgt=0.25,btgt=8e+05,btrigger = 0.9*8e+05, blim=2e5,bclose=3e5,fmin=0.03,obs=ple4)
