SSplotRetroDevs: Make squid plot of retrospectives of recruitment deviations.

Description

Inspired by Jim Ianelli and named by Sean Cox, the squid plot is a way to examine retrospective patterns in estimation of recruitment deviations.

Usage

SSplotRetroDevs(retroSummary, endyrvec, cohorts, ylim = c(-3, 3),
uncertainty = FALSE,
labels = c("Recruitment deviation relative to recent estimate",
"Recruitment deviation", "Age"),
main = "Retrospective analysis of recruitment deviations",
mcmcVec = FALSE, relative = FALSE,
labelyears = TRUE, legend = FALSE, leg.ncols = 4)

Arguments

retroSummary
List object created by SSsummarize that summarizes the results of a set of retrospective analysis models.ss
endyrvec
Vector of years representing the final year of values to show for each model.
cohorts
Which cohorts to show in plot.
ylim
Limits of y-axis.
uncertainty
Show uncertainty intervals around lines? (This can get a bit busy.)
labels
Vector of plot labels.
main
Title for plot.
mcmcVec
Either vector of TRUE/FALSE values indicating which models use MCMC. Or single value applied to all models.
relative
Show deviations relative to most recent estimate or relative to 0.
labelyears
Label cohorts with text at the end of each line?
legend
Add a legend showing which color goes with which line (as alternative to labelyears).
leg.ncols
Number of columns for the legend.
