Validating open-source R packages has been a hot topic over the past few years. This talk focuses on MetrumRG’s updated process and tooling for validating first party R packages, that is R packages that we develop in-house, almost all of which are also open-source. This has been the fruit of interdisciplinary collaboration within Metrum, and has also benefited tremendously from the work of folks in the R Validation Hub and other cross-industry working groups. The result is a streamlined process for our developers, a better experience for our scientific users, and improved validation documentation for our Quality team.
