Except below from [Xu et al. (2018)](https://cdnsciencepub.com/doi/10.1139/cjfas-2017-0446) describes a tuning algorithm for the hyper-parameter sigma_s used with semi-parametric selectivity (which has a label like "sigmasel_Fishery" in SS). A table similar...

ss3_utility_functions

The r4ss package has just revised the column names used in the functions to read SS3 input files (see https://github.com/r4ss/r4ss/releases/tag/v1.50.0). ss3sim uses the old names in many places (e.g. 15...

@AgurtzaneUrtizberea and @GiancarloMCorrea noted that the SS_writedat function rounds values to 6 significant digits. That happens in the custom https://github.com/r4ss/r4ss/blob/main/R/write_fwf4.r function written by @yukio-takeuchi (which was inspired by https://github.com/r-gregmisc/gdata/blob/main/R/write.fwf.R (currently...

question

The `run-extra-tests-for-code-coverage` github action to test the code against a larger set of test models and check code coverage consistently takes 4-5 hours to run: https://github.com/r4ss/r4ss/actions/workflows/r4ss-extra-tests.yml which @e-perl-NOAA noted slows...

PR is also intended to test trigger of doc-and-style workflow.

### Describe the feature request. Discussion of new alpha-beta parameterization of Beverton-Holt being added to SS3 (see issue https://github.com/nmfs-ost/ss3-source-code/issues/191 and draft pull-request https://github.com/nmfs-ost/ss3-source-code/pull/442), includes note that "If biology is time-varying,...

Thanks to @MOshima-PIFSC for pointing out that an issue that only NOAA folks (as far as I know) have been having for a few weeks with R on Windows not...
