CRAN Policy Submission Lint

Runs the same checker as the npm package @readystack/cran-policy-submission-lint on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

Catch the CRAN Repository Policy violations before the volunteer team does

Install

cran-policy-submission-lint file

Node 18+. The same 25 rules as the VS Code extension, from a terminal or CI.

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.

@readystack/cran-policy-submission-lint --dir ./templates --report html --out report.html

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.
