R Package Builder

Preview

Scaffold, write with AI, document, test in-browser, and export a real R package.

Instructions

From idea to installable R package — in your browser

R runs locally via WebR (WebAssembly), so there’s nothing to install and your code never leaves your machine. Each package autosaves and the status pills track how far along it is.

Full instructions
Scaffold
A valid DESCRIPTION, NAMESPACE, an example function and a test.
Write with AI
Describe a function in words; get it back with full roxygen docs.
Bundle data
Drop in a CSV; it becomes a documented data/*.rda dataset.
Check in-browser
Run a real R CMD check subset via WebR — no install needed.
Export
Build a CRAN-style name_version.tar.gz, all client-side.
Publish
Push to a GitHub repo with a CI workflow that runs full checks.
