data.SS_new file containing expected values and sample from
true ages to get realistic proportions for the number of fish in each age
bin, then use the mean size-at-age and CV for growth to generate random
samples of size, which are then converted to weight and averaged to get mean
weight-at-age values. Missing ages and years are filled according to a
specified function. These matrices are then written to file for the EM. By
calling this function, ss3sim_base for more details on how that is implemented.
If used with run_ss3sim the case file should be named
wtatage.sample_wtatage(wta_file_in, outfile, dat_list, ctl_file_in, years,
fill_fnc = fill_across, write_file = TRUE, fleets, cv_wtatage = NULL).wtatage.ss file if write_file = TRUE. A list
object containing the modified .wtatage.ss file is returned invisibly.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.fill_acrossOther sampling functions: clean_data,
