So far in our exploration of data visualization we've focused on scatterplots. We'll now expand to consider visualizing categorical variables using boxplots (which are preferred) and barplots (which may be a bit more traditional).
Upon completion of this lesson, you should be able to:
- Create boxplots and barplots with multiple panels
- Add mean and errorbars for SE to boxplots as an alternative to barplots
- Add errorbars to barplots
The R code file and data files for this lesson can be found on the Essential R - Notes on learning R page.
