Combining PIRLS and TIMSS data (EdSurvey)


Welcome to the RStudio community!

Why don't you share a snippet of the data you are trying to work with and show what it is you like to do. The easiest way is to create a reprex. A reprex consists of the minimal code and data needed to recreate the issue/question you're having. You can find instructions how to build and share one here:

Good luck,
