Dataset Transformations

In this section we’ll talk about transforming your entire dataset. You’ll learn how to take a dataset in long form and transform it into wide form, and vice versa. You’ll also learn how to combine datasets–a critical skill for social scientists.

Doing all these tasks properly depends on clearly understanding the structure of your data. We’ll continue to use the concepts and terminology introduced in Hierarchical Data Concepts, so be sure you’ve read that section before proceeding.
