change_maturity(ctl_file_in = "em.ctl", ctl_file_out = "em.ctl",
  maturity_option = 1L)

• A modified SS3 control file.

Which arguments to specifiy in case files

All function argument descriptions that start with an asterisk (*) will be passed through the case files to run_ss3sim. If one of these arguments is not specified in a case file, then a value of NULL will be passed, which may or may not be an appropriate value. Other arguments will be ignored if specified.
