Slides To Revisit

For time reasons, I skipped over a handful of slides. It would be a good idea to review the “Project Organization & Tooling” (slides 38-48) in the post lecture slides. These dlies go over strategies for how to organize your project’s files.

Homework

For Problem Set 1, you are asked to create a handful of visualizations using a Quarto notebook. I suggested a histogram, scatterplot, and a bar chart.

Slides 74-92 have code you can repurpose. You can also use LLMs if that helps. If you would prefer to try something other than a bar chart, histogram, or scatterplot, that is fine. I just want you to get practice “getting something on the page”.

Tomorrow we will go into more detail on the logic and syntax of ggplot2.

.gitignore and Quarto

Quarto can sometimes be a bit finnicky with what files it leaves behind when you render a notebook. You may wan to keep rendered files out of your git repository.

You can do this by adding the following to your .gitignore file:

.quarto/
*_cache/
*_files/
*_site/
/cache/

You can adjust as needed. Tgis prevents any “work” files that Quarto creates.

If you wanted to also excluded rendered files, you could add the following to your .gitignore file:

*.docx
*.html

Closing Thoughts

Day 1 is tooling heavy and visualization-light. I appreciate your patience. Tomorrow we will get far more into the theory and practice of visualization.
