The second edition at https://moderndive.com/v2/ is now the Quarto edition — the bookdown build is retired, and every legacy URL redirects to its new home. This release also marks moderndive 0.8.0 on CRAN, the version whose multi-predictor get_correlation() the Chapter 5, 6, and 10 material uses — meaning the book and all of its companion data packages (olympicAthletes, steves, exoplanetdata, volcanoes) now install entirely from CRAN.
What the online edition gained since v2.0.0 (the second print edition)
- Run R in your browser — webR-powered code cells throughout the chapters and Appendix B; edit and re-run without installing anything. The companion data packages load in the browser too.
- 115 Quick check questions (ten to twelve per chapter) with collapsible, misconception-aware answers.
- 511 end-of-chapter exercises across the eleven chapters, difficulty-rated (★/★★/★★★), organized by book section, most with their own in-browser sandbox.
- Five new exercise datasets introduced progressively from Chapter 1: Olympic athletes, Rick Steves' Europe episodes, confirmed exoplanets, Holocene volcanoes, and
bob_ross. - Learning scaffolding — chapter learning objectives, "common mistake" callouts, per-chapter cheatsheets, and an auto-linked glossary with hover definitions.
- Accessibility — alt text on every figure, semantic screen-reader math, WCAG-checked contrast in light and dark mode, keyboard and reduced-motion support.
- Expanded Appendix B — every inference case study is interactive, plus new sections on correlation/simple linear regression and multiple regression with
infer::fit().
Full details, version by version, in NEWS.md — the cutover itself is the 2.9.0 entry.
