SSplotYield: Plot yield and surplus production.

In r4ss: R Code for Stock Synthesis

Plot yield and surplus production.

Description

Plot yield and surplus production from Stock Synthesis output. Surplus production is based on Walters et al. (2008).

Usage

SSplotYield(
  replist,
  subplots = 1:4,
  refpoints = c("MSY", "Btgt", "SPR", "Current"),
  add = FALSE,
  plot = TRUE,
  print = FALSE,
  labels = c("Fraction unfished", "Equilibrium yield (mt)", "Total biomass (mt)",
    "Surplus production (mt)", "Yield per recruit (kg)"),
  col = "blue",
  col2 = "black",
  lty = 1,
  lwd = 2,
  cex.main = 1,
  pwidth = 6.5,
  pheight = 5,
  punits = "in",
  res = 300,
  ptsize = 10,
  plotdir = "default",
  verbose = TRUE
)

Arguments

replist	A list object created by SS_output().
subplots	vector controlling which subplots to create Numbering of subplots is as follows: 1 yield curve 2 yield curve with reference points 3 surplus production vs. biomass plots (Walters et al. 2008)
refpoints	character vector of which reference points to display in subplot 2, from the options 'MSY', 'Btgt', and 'SPR'.
add	add to existing plot? (not yet implemented)
plot	plot to active plot device?
print	print to PNG files?
labels	vector of labels for plots (titles and axis labels)
col	line color for equilibrium plot
col2	line color for dynamic surplus production plot
lty	line type (only applied to equilibrium yield plot at this time)
lwd	line width (only applied to equilibrium yield plot at this time)
cex.main	character expansion for plot titles
pwidth	width of plot
pheight	height of plot
punits	units for PNG file
res	Resolution of plots printed to files. The default is res = 300.
ptsize	point size for PNG file
plotdir	directory where PNG files will be written. by default it will be the directory where the model was run.
verbose	report progress to R GUI?
