Everything here runs inside your browser. There is nothing to install, no account to make, and nothing you can break. Each tutorial is self-contained — open it, work through it, close it.

If a page seems frozen when you first open it, give it a few seconds. R itself is downloading.

Week 2 — R Basics & The Weighted Dice

Your first hour in R. Arithmetic and objects, vectors, functions and their arguments, writing a function of your own, and running a simulation ten thousand times — ending with a pair of dice you have quietly weighted.

Adapted from Grolemund, Hands-On Programming with R, ch. 1–3.

Week 3 — Working With an LLM, Part I: Prompt It

Twenty minutes on the one skill that makes AI genuinely useful for code. You will load a 229,444-row dataset and estimate a treatment effect, having been taught neither — and find out why how you ask decides whether you get an answer or a fabrication.

Uses Gerber, Green & Larimer (2008) on social pressure and voter turnout.

Week 6 — Warming up: Quarto

A quick check on last week’s pair-programming task. Take apart a .qmd file, fix a broken header, find the one code chunk that actually runs, and predict what the rendered page will look like.

Reviews Pair Programming 2: Quarto in R.

Week 10 — ggplot2

Pair-programming activity.

Based on Wickham, Çetinkaya-Rundel & Grolemund, R for Data Science (2e), ch. 1.
