to fit the model peeling off 1, 2, ..., n.peels years of data.

)Optimized TMB model, output from fit_tmb.
Integer, number of peels to use in retrospective analysis. Default = 7.
Character, specifies which parameters to treat as random effects. Default = "model$input$random".
T/F, use MLEs from full model fit as initial values for each peel? If not, the initial values from full model input are used. Default = TRUE.
T/F, calculate standard deviations of model parameters for each peel? Default = FALSE.
integer, number of additional Newton steps after optimization for each peel. Default = 0.
T/F, Passed to silent argument of TMB::MakeADFun. Default = FALSE.
T/F, Passed to argument of internal fit_peel function. Determines whether peel number is printed to screen. Default = FALSE.
T/F, should modified input list be saved for every peel? Necessary to project from a peel but increases model object size. Default = FALSE.
T/F, calculate and report biological reference points
T/F, whether to verify the wham package commit and version for the fitted model are the same as the currently used package.
peels, a list of length n.peels, where entry i is a model
fit by peeling off i years of data.
