CRAN Package Status

Check a package's submission/review state, a specific historical version's fate (e.g. {package} {version}, as in btw v1.4.0), or its current R CMD check results across CRAN's test platforms.

"CRAN status" is ambiguous between two questions:

• Submission status: is/was this package (or version) in review, published, archived, or rejected? See "Submission Status".
• Check results: is the published version passing R CMD check on all platforms, or does it have WARN/ERROR/NOTE flags risking removal? See "Check Results".

CRAN's servers are a shared, unpaid resource. Never issue requests in parallel or in a tight loop — pause briefly (e.g. sleep 1) between requests, stop looping as soon as a match is found, and avoid re-fetching a page you've already checked in this session.
