How to read thisHide how to read this

A practice counts when its file is in the repository.

A code of conduct, contributing guide or pull request template also counts when GitHub shows the organization's default from its .github repository on a repository that has none of its own. The note under its family then says how many are the repositories' own and how many are the default.

A repository without the file may still follow the practice another way.

A pull request opened by a tool's account, commits by a tool's account, or commits whose message credits a tool: 22
A tool's file in the repository and nothing else: 22

How to read thisHide how to read this

Some tools leave nothing we can find in a repository's files, pull requests or commit messages.

A repository where two tools were found is counted once in the total and once under each tool, so the tool rows add up to more than 44.

Finding nothing does not mean no tool was used.

The same commit can be in both counts, for example when a tool's own account made it and its message also credits the tool.

Commits crediting a tool are counted from the searches run so far, so that figure is a minimum.

Each count covers the whole default branch, which in some repositories includes code outside the R package.

The two commit counts answer different questions and are never added. Commits crediting a tool are a minimum.
