Week 6: R Markdown and Visualization

Official Topic

R Markdown and data visualization. Quiz 2.

Problem Focus

How do we turn code, figures, and explanation into a reproducible report?

Students write a first Quarto/R Markdown-style report and use ggplot2 to create honest, labeled visualizations.

In Class

  • Create a computational document.
  • Use code chunks and narrative text.
  • Create scatterplots and histograms.
  • Interpret a plot in words.

AI-Aware Task

Ask an LLM to improve a plot. Evaluate whether the suggested labels, scales, and conclusion are statistically honest.
