13  Package publishing rules

13.1 Avoid name collisions

While it is technically possible to host a fork or a completely different package with the same name in a universe, this practice is strongly discouraged.

• Users might accidentally install the example package from CRAN instead of the intended version from a universe.
  
• R will overwrite one package with the other when running install.packages() or update.packages().
  
• This issue becomes more problematic when other packages depend on the conflicting package.

To address this, R-universe:
- Treats the CRAN version as the official package.
- Warns users about the duplication on the page of the conflicting package.

13.2 Reserved names

Avoid using the following names for packages, as they have special meanings in R-universe URLs (https://username.r-universe.dev/{pkg}/):

• api
  
• apis
  
• articles
  
• badges
  
• bin
  
• builds
  
• citation
  
• contributors
  
• datasets
  
• docs
  
• favicon.ico
  
• feed.xml
  
• index.xml
  
• manual
  
• packages
  
• readme
  
• robots.txt
  
• sitemap_index.xml
  
• sitemap.xml
  
• src

13.3 Code of Conduct

Universe maintainers are solely responsible for the projects in their universes.

The R-universe project itself is governed by the rOpenSci code of conduct.
