cran.r-project.org
In short: CRAN (cran.r-project.org) accepts r package listing and manual page. It is free to submit, takes a moderate amount of preparation, and scores 84/100 on our impact ranking (high impact).
Submit a useful R package with URL and BugReports metadata pointing to its official project and documentation pages.
CRAN performs rigorous automated and manual review; packages must meet policy across supported platforms.
Priority is high, which sets the band. It is free and moderate to complete, which adjusts it within that band. The score ranks your queue — it is not a measure of domain authority.
