Plot likelihood profile results

Makes a plot of change in negative-log-likelihood for each likelihood component that contributes more than some minimum fraction of change in total.

Arguments

summaryoutput: List created by the function SSsummarize().
plot: Plot to active plot device?
print: Print to PNG files?
models: Optional subset of the models described in summaryoutput. Either "all" or a vector of numbers indicating columns in summary tables.
profile.string: Character string used to find parameter over which the profile was conducted. If exact=FALSE, this can be a substring of one of the SS parameter labels found in the Report.sso file. For instance, the default input 'steep' matches the parameter 'SR_BH_steep'. If exact=TRUE, then profile.string needs to be an exact match to the parameter label.
profile.label: Label for x-axis describing the parameter over which the profile was conducted.
exact: Should the profile.string have to match the parameter label exactly, or is a substring OK.
ylab: Label for y-axis. Default is "Change in -log-likelihood".
components: Vector of likelihood components that may be included in plot. List is further refined by any components that are not present in model or have little change over range of profile (based on limit minfraction). Hopefully this doesn't need to be changed.
component.labels: Vector of labels for use in the legend that matches the vector in components.
minfraction: Minimum change in likelihood (over range considered) as a fraction of change in total likelihood for a component to be included in the figure.
sort.by.max.change: Switch giving option to sort components in legend in order of maximum amount of change in likelihood (over range considered). Default=TRUE.
col: Optional vector of colors for each line.
pch: Optional vector of plot characters for the points.
lty: Line type for the likelihood components.
lty.total: Line type for the total likelihood.
lwd: Line width for the likelihood components.
lwd.total: Line width for the total likelihood.
cex: Character expansion for the points representing the likelihood components.
cex.total: Character expansion for the points representing the total likelihood.
xlim: Range for x-axis. Change in likelihood is calculated relative to values within this range.
ymax: Maximum y-value. Default is 10% greater than largest value plotted.
xaxs: The style of axis interval calculation to be used for the x-axis (see ?par for more info)
yaxs: The style of axis interval calculation to be used for the y-axis (see ?par for more info).
type: Line type (see ?plot for more info).
legend: Add a legend?
legendloc: Location of legend. Either a string like "topleft" or a vector of two numeric values representing the fraction of the maximum in the x and y dimensions, respectively. See help("legend") for more info on the string options.
pwidth: Default width of plots printed to files in units of punits.
pheight: Height of plots printed to png files in units of punits. Default is designed to allow two plots per page, with pheight_tall used for plots that work best with a taller format and a single plot per page.
punits: Units for pwidth and pheight. Can be "px" (pixels), "in" (inches), "cm" (centimeters), or "mm" (millimeters). The default is punits="in".
res: Resolution of plots printed to files. The default is res = 300.
ptsize: Point size for plotted text in plots printed to files (see help("png") in R for details).
cex.main: Character expansion for plot titles. The default is cex.main=1.
plotdir: Directory where PNG files will be written.
add_cutoff: Add dashed line at ~1.92 to indicate 95% confidence interval based on common cutoff of half of chi-squared of p=.95 with 1 degree of freedom: 0.5*qchisq(p=cutoff_prob, df=1). The probability value can be adjusted using the cutoff_prob below.
cutoff_prob: Probability associated with add_cutoff above.
add_no_prior_line: Add line showing total likelihood without the prior (only appears when profiled parameter that includes a prior)
verbose: A logical value specifying if output should be printed to the screen.
...: Additional arguments passed to the plot command.

Note

Someday the function profile() will be improved and made to work directly with this plotting function, but they don't yet work well together. Thus, even if profile() is used, the output should be read using SSgetoutput() or by multiple calls to SS_output().
