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:
- 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
You should put your code on GitHub in some form. Make sure that 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).
