SS_fitbiasramp: Estimate bias adjustment for recruitment deviates

Description

Uses standard error of estimated recruitment deviates to estimate the 5 controls for the bias adjustment in Stock Synthesis

Usage

SS_fitbiasramp(replist, verbose=FALSE, startvalues=NULL, method="BFGS",
  twoplots=TRUE, transform=FALSE, png=FALSE, pdf=FALSE, oldctl=NULL,
  newctl=NULL, pwidth=7, pheight=7, punits="in", ptsize=12, res=300,
  cex.main=1)

Arguments

replist
Object created using SS_output
verbose
Controls the amount of output to the screen. Default=FALSE.
startvalues
A vector of 5 values for the starting points in the minimization. Default=NULL.
method
A method to apply to the 'optim' function. See ?optim for options. Default="BFGS".
twoplots
Make a two-panel plot showing devs as well as transformed uncertainty, or just the second panel in the set? Default=TRUE.
transform
An experimental option to treat the transform the 5 quantities to improve minimization. Doesn't work well. Default=FALSE.
png
Send plot to PNG file? Default=FALSE.
pdf
Send plot to PDF file? Default=FALSE.
oldctl
Optional name of existing control file to modify. Default=NULL.
newctl
Optional name of new control file to create from old file with estimated bias adjustment values. Default=NULL.
pwidth
Default width of plots printed to files in units of punits. Default=7.
pheight
Default height width of plots printed to files in units of punits. Default=7.
punits
Units for pwidth and pheight. Can be "px" (pixels), "in" (inches), "cm" or "mm". Default="in".
ptsize
Point size for plotted text in plots printed to files (see help("png") in R for details). Default=12.
res
Resolution of plots printed to files. Default=300.
cex.main
Character expansion for plot titles.
