cataScience 2.1.3

• The markdown lesson pages are now rendered from text instead of from the file path. markdown::mark() (>= 2.0) rewrites an input file in place when it runs under R CMD check, which made the test suite fail on CRAN’s Debian machines where the installed package library is mounted read-only (and violated the CRAN policy against writing outside the session temp directory). Rendering from text writes nothing; the generated HTML is unchanged.

cataScience 2.1.2

• Added a testthat test suite covering the app code that R CMD check cannot reach through the examples: the data-cleaning helpers (outlier detection, winsorizing, imputation, file import), the quiz and cleaning module servers via shiny::testServer(), the question bank, and a smoke test that builds the whole app UI.
• The example of run_cata() now also runs outside an interactive session.
• The outlier boxplot no longer warns about missing values while a dataset still has them.

cataScience 2.1.1

• Images inside the markdown lesson pages now scale to the card width instead of being clipped (affected the Background tabs of the Visualize, Cleaning, and Import pages).
• The app stylesheet link carries a cache-busting version query so browsers pick up styling changes after an update.
• Resized one oversized bundled figure (9000 px wide) to 1800 px.

cataScience 2.1.0

• First release: run_cata() launches the bundled “A Journey of Data Science” training app.
