Expanding data wrangling

This tutorial introduces joining, pivoting, factor variable manipulation, and basic string manipulation with stringr.

By the end of the tutorial, you should be able to:

• Use pivot_longer() and pivot_wider()to change the way the data are laid out.
  
• Join tables of data together using the dplyr join functions and understand the differences among the different types of joins.
  
• Use various forcats functions, including ones not covered in the tutorial, to change the order or values of levels of categorical variables.
  
• Use the stringr functions covered in this tutorial (plus separate()) and know where to find information about other stringr functions (HINT: the cheatsheet is a great start).
