Intro
We will be talking about visualizing your data, with an emphasis on
ggplot2, which is based on the Grammar of Graphics.
Goals
- Participants will learn to think broadly about effective uses of
visualization
- Participants will learn about the Cleveland hierarchy and research
on effective visualization techniques
- Participants will be introduced to ggplot2
Resources
- Course material
- ggplot:
- 2026
- 2024
Exercise
- Construct some (i.e., more than one) ggplots using your data. (If
you already made one for a previous assignment, try making another.)
Discuss:
- what you are trying to show
- some of the choices that you have made
- the basis for these choices (e.g., Cleveland hierarchy, proximity of
comparisons, or other principles of graphical communication)
- See the assignment
instructions
Put your code on GitHub in some form. Make sure your code has no
absolute paths, and runs from beginning to end when you restart R (use
source(...) so you don’t skip over errors by accident; see
‘running R’)
