roxygen2 4.0.1

2014-05-19 Hadley Wickham
We’re pleased to announce a new version of roxygen2. Roxygen2 allows you to write documentation comments that are automatically converted to R’s standard Rd format, saving you time and reducing duplication. This release is a major update that provides enhanced error handling and considerably safer default behaviour. Roxygen2 now adds a comment to all generated files so that you know they shouldn’t be edited by hand. This also ensures that roxygen2 will never overwrite a file that it did not create, and can automatically remove files that are no longer needed. Read more →
