Licenses
The overall project is available under the CC BY-SA 4.0 license found at LICENSE; all code without any narrative text is also (at your option) available under the CC0 1.0 Universal license found at LICENSE-CODE.
Why two licenses? The CC BY-SA 4.0 license is for the content of the website, while the CC0 1.0 Universal license is for the code and configuration files. This is a common practice for websites that include code snippets and other content that may be reused in other projects, particularly because the CC BY-SA 4.0 license is not intended to be used with software.
Notes
This tutorial was primarily written in 2025 using R 4.4+ with the {datawizard} package for automated data dictionary creation. Major changes to the {datawizard} package can be found at the package’s website for the most up-to-date information, and to confirm that our tutorial is not out-of-date.
