misc.tutorials (development version)
The R for Data Science material is now ten tutorials instead of five. Each two-topic tutorial was split in two, keeping its first topic and spinning the second out under a topic name:
r4ds-1(Billboard) andmusic,r4ds-2(US births) andnba-recruits,r4ds-3(school districts) andtime-use,r4ds-5(wildfires) andimdb-rankings. Withprediction-markets(split fromr4ds-4in August) the family runs 18–25 exercises per tutorial, and the VS Code list shows each spin-out directly after its parent (ordering1–10), followed bycensus,baseball,ducks,sharks, andmovies.spidermanis retired; its Spider-Man comparison is now the closing topic ofmovies.ducksandsharksare rebuilt on the multi-page website form thatbaseballintroduced, and every tutorial now follows the three-exercise caching arc exactly once.censusandbaseballwere shortened as well; every tutorial now runs 18–28 exercises.Package-wide clean-up: every question carries a complete plain-text copy of its prompt; faked listings include the
AGENTS.mdthat every fresh repo contains; fakedgit logandquarto publishtranscripts match their real shape; knowledge drops are trimmed to two sentences about the data or the output; retired AI-tool recommendations are replaced by “Use AI however you like.”; stalequarto previewinstructions and maintainer comments are gone.r4ds-1shipsbillboard.csv(a copy oftidyr::billboard) instead of loading the data from a package;r4ds-3andtime-usehave students gitignore their.duckdbfiles;sharksno longer shipsattacks.csvorattacks.rds.Rebuilt every tutorial on learnr2, which renders each one to a static Quarto page whose code runs in the browser via WebR. learnr2 is the package’s only tutorial dependency (it also supplies
show_file()), and the tests and CI render tutorials withlearnr2::check_tutorial()andlearnr2::render_tutorials(). Plot exercises now ask for a screenshot of the rendered plot instead of the code that drew it.
