Change the years in the forecast file — change_yrs

This is both to increment years forward and/or to change absolute years to relative years.

Usage

change_yrs_fcast(
  fore,
  make_yrs_rel = TRUE,
  nyrs_increment = NULL,
  nyrs_fore = NULL,
  mod_styr,
  mod_endyr
)

fore: A forecasting file read into R using r4ss::SS_readforecast()
make_yrs_rel: Should the absolute years in the forecast file be changed to relative years? Defaults to TRUE.
nyrs_increment: The number of years to increment forecasting period years. If NULL (the default value), will not be incremented.
nyrs_fore: The number of years of forecasting to do. If NULL, do not change the number of forecasting years already specified in fore
mod_styr: The first year of the model
mod_endyr: The last year of the model fore assumes when read in. Note that the assumed model year will be different for the output if nyrs_increment is not NULL.
