 This project is related to other existing projects in R or other languages, but also differs from them in the following aspects:
 
+- [labelled](https://github.com/larmarange/labelled/): A package for labelling data in R, but it is more focused on labelling variables than validating them.
 - [linelist](https://github.com/epiverse-trace/linelist): A package for managing and validating linelist data - the original inspiration for datatagr.
