Week 6: R Markdown and Visualization

Today’s Question

How do code, plots, and explanation become a reproducible report?

Reproducible Report

A report should include:

• question;
• data;
• code;
• output;
• interpretation;
• checks.

R Pattern

library(ggplot2)

ggplot(mtcars, aes(x = wt, y = mpg)) +
  geom_point() +
  labs(x = "Weight", y = "Miles per gallon")

Plot Checklist

• Clear labels
• Appropriate geometry
• Honest scale
• Interpretable caption

AI Check

An LLM can improve wording. It cannot decide whether your plot supports the conclusion unless you verify it.
