SSplotMCMC_ExtraSelex: Plot uncertainty around chosen selectivity ogive from MCMC.
In r4ss: R code for Stock Synthesis

Plot uncertainty in selectivity from an MCMC output for whichever fleet/year was chosen in the optional extra "more stddev reporting"

1 2	SSplotMCMC_ExtraSelex(post, add = FALSE, nsexes = 1, shift = 0, fleetname = "default", col = "blue")

`post`	A data frame containing either derived_posteriors.sso or a good subset of it. This can be an element of the list created by the the `SSgetMCMC` function.
`add`	TRUE/FALSE option to add results to an existing plot.
`nsexes`	Number of sexes in the model (should match model values but is only used in the title).
`shift`	Optional adjustment to the x values to avoid overlap of intervals when overplotting on an existing plot.
`fleetname`	Optional input to make the title better. Default will be something like "Fleet 1", using the numbering from the model.
`col`	Color for points and lines.
