Detect R in any GitHub repo

R is one of the language technologies Stack Fingerprint recognises automatically when it scans a public repository.

How R is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags R when it finds any of these:

  • Files or folders: /\.Rproj$/, DESCRIPTION
  • File extensions: .r, .R

R README badge

A static badge you can paste anywhere in Markdown:

R badge

Markdown
![R](https://img.shields.io/badge/R-276DC3?style=for-the-badge&logo=r&logoColor=white)

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so R (and everything around it) appears or disappears on its own:

README.md
[![Stack Fingerprint](https://stackfingerprint.vercel.app/api/card?repo=OWNER/REPO)](https://stackfingerprint.vercel.app/?repo=OWNER/REPO)

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
