This is the second in a two-part series of R tutorials that I delivered for The University of Connecticut Department of Psychology. The first in this series, Dealing with Data in dplyr, focused on using the dplyr package for data cleaning and manipulation. This second tutorial will focus on using ggplot2 for data visualization. This is aimed at people who have little to no experience with programming, but have completed the free Introduction to R course on Data Camp. Perhaps check that (and the dplyr tutorial) out first, if you are entirely new to using R.
I have released this tutorial as an R notebook on GitHub: Getting Good at ggplot2. The data and R markdown files are available in my data_tutorials repository. Please enjoy the sense of humor and obscure references.
