1. Final thoughts
Congratulations on finishing the course! You've worked hard to reach the end.
2. What you've learned
In these four chapters, you've learned all about working with qualitative variables. We started out by learning how to examine your variables and then moved onto how to order them, change, rename, and collapse their levels, and create them.
Along the way, you reviewed some useful data wrangling functions from other tidyverse packages, including tidyr, dplyr, and stringr and learned some tricks of ggplot2.
Finally, you used your new skills to recreate a plot from 538, illustrating which behaviors on airplanes people find most rude.
3. Congratulations!
You're now well-prepared to continue on your R journey. Maybe you want to learn about the tidyverse functions to work with dates and times, or you want to continue to build your string manipulation skills. Perhaps you're ready to become a communication master, customizing your own RMarkdown reports. Other DataCamp courses can help you with all this and more. Good luck, and congratulations again!
