Package automation

These workflows validate development changes on GitHub. Consult the checks for the specific commit; configuration alone does not establish a successful run.

Workflow	Trigger	Work performed
R-CMD-check.yaml	Pull requests, pushes to main/master, or manual dispatch	R-release package checks on Windows, Linux, and macOS, including normal tests, examples, and vignette checks. NOT_CRAN=false excludes tests marked skip_on_cran(). Warnings fail the job; check logs are retained.
full-fitting-tests.yaml	Pull requests or manual dispatch	The complete test suite and structural baseline comparison on macOS R release with NOT_CRAN=true, the platform the numerical references were generated on. A separate Linux job tests testthat 3.2.0 with R 4.5.3 (its C APIs are incompatible with R 4.6). Both check the PR head and retain evidence, including on failure.
pkgdown.yaml	Pull requests, pushes to main/master, or manual dispatch	Builds reference pages and articles into a downloadable documentation artifact. No deployment step is configured.
submission-archive.yaml	Pull requests or manual dispatch	Builds a source archive with current R release, checks it, and checks the identical archive on R-devel, Windows and macOS. Retains the tarball, SHA-256, source revision and check logs for submission preparation.

All workflows request only contents: read. Checkout credentials are not retained. Action major versions follow the official r-lib examples and upload-artifact usage.

Local checks before publishing these workflows

1. Parse the YAML and validate GitHub Actions syntax with actionlint when available.

2. Run R CMD build and R CMD check --as-cran on the source archive. Confirm that .github, _pkgdown.yml, generated docs, and the redundant full license text in LICENSE.md are excluded from the R source archive.

3. Run the complete test suite explicitly:

   Sys.setenv(NOT_CRAN = "true")
   testthat::test_local(".", reporter = "summary", stop_on_failure = TRUE)

4. Generate the documentation after the Rd files have been regenerated:

   pkgdown::build_site(preview = FALSE, examples = FALSE, new_process = TRUE)

   The release site is written under docs/. Reference examples remain visible, while the package check executes examples and the site build executes article chunks. Inspect the home, reference, and fitted-object workflow pages.

5. Inspect each platform's actual run and the full fitting and minimum-dependency jobs triggered by the pull request update. Keep hosted results distinct from local results; do not infer them from configuration alone.

The License: GPL (>= 3) declaration in DESCRIPTION remains authoritative. LICENSE.md makes the existing license readable in the repository and documentation; R already ships the standard GPL text, so the redundant copy is excluded from the package archive in accordance with the R package licensing guidance.
