This is a reference guide for commonly used functions in education research data wrangling.

How this Wiki is organized:

Level	Content	Example
1 Page	Overarching theme	Labelling data
2	Task you want to accomplish	Add value labels
3	Task further refined and a link to a page that provides one or more packages::functions() you may use to solve that problem along with example code	Add NA value labels

Note: There are almost endless ways to achieve these transformations. This Wiki just provides a few ideas of common ways I might solve a problem.
