Arguments

replist

List produced by SS_output.

xlab

Label on horizontal axis.

ylab

Label on vertical axis.

showmle

Show MLE estimate and asymptotic variance estimate with blue lines?

showpost

Show posterior distribution as bar graph if MCMC results are available in replist?

showprior

Show prior distribution as black line?

showinit

Show initial value as red triangle?

showdev

Include devs in the plot?

showlegend

Show the legend?

fitrange

Fit range tightly around MLE & posterior distributions, instead of full parameter range?

xaxs

Parameter input for x-axis. See ?par for more info.

xlim

Optional x-axis limits to be applied to all plots. Otherwise, limits are based on the model results.

ylim

Optional y-axis limits to be applied to all plots. Otherwise, limits are based on the model results.

verbose

Controls amount of text output (maybe).

nrows

How many rows in multi-figure plot.

ncols

How many columns in multi-figure plot.

ltyvec

Vector of line types used for lines showing MLE and prior distributions and the median of the posterior distribution.

colvec

Vector of colors used for lines and polygons showing MLE, initial value, prior, posterior, and median of the posterior.

new

Open new window for plotting?

add

Add to existing plot?

pdf

Write to PDF file instead of R GUI?

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.

returntable

Return table of parameter info? Default=FALSE.

strings

Subset parameters included in the plot using substring from parameter names (i.e. "SR" will get "SR_LN(R0)" and "SR_steep" if they are both estimated quantities in this model).

exact

Should strings input match parameter names exactly? Otherwise substrings are allowed.

newheaders

Optional vector of headers for each panel to replace the parameter names.
