getreadystack/cran-policy-submission-lint repository overview

⁠CRAN Policy Submission Lint

Catch the CRAN Repository Policy violations before the volunteer team does

⁠Run

docker run --rm -v "$PWD":/work getreadystack/cran-policy-submission-lint /work/file

The same 25 rules as the VS Code extension, in a container. Mount a folder on /work.

⁠Free

• Check the R file, DESCRIPTION or NAMESPACE open in your editor against all 25 CRAN policy rules, with the line number and the fix.
• --rules lists every rule

⁠With a licence ($29 once)

• Sweep the whole package - every R/ file, DESCRIPTION and NAMESPACE together - and write a dated pre-submission report you keep and can paste into your submission comments.

docker run --rm -e READYSTACK_LICENSE=<key> -v "$PWD":/work getreadystack/cran-policy-submission-lint --dir /work --ci

A freelance R developer in North America bills $50-$100 an hour (Upwork, 2026); one rejected submission is a round trip of rework plus a wait in the queue.
