moderndive 0.8.0

  • View() now renders correctly inside webR (the in-browser R that powers the ModernDive book’s live exercises). webR has no pandoc, so a DT::datatable() htmlwidget cannot be saved as the self-contained HTML the cell needs (DT::saveWidget() errors), and the auto-print path is gated by interactive() being FALSE. In webR, View() now builds a self-contained static HTML table and pushes it through webR’s viewer hook, so the data displays inline instead of only printing the explanatory message. Outside webR the DT::datatable() behaviour is unchanged.
  • Fix issue #58
  • Add in unit tests to bring test coverage back to 100%
  • get_regression_points() and get_regression_summaries() now handle in-formula transformations on either side of the model formula (e.g. lm(log(y) ~ poly(x, 2))). LHS transforms previously errored; they now produce a sanitized outcome column on the model’s scale (e.g. log_mpg, log_mpg_hat). RHS transforms no longer leak basis matrices or wrapper columns (poly() matrix columns, scale(), I()) into the points table; the original predictor variable is shown instead. The .rownames column is no longer leaked into the output.
  • get_regression_table(), get_regression_points(), and get_regression_summaries() now accept glm() model objects (resolves issue #20). For glm() models, get_regression_points() returns fitted values and residuals on the response scale (e.g. probabilities for logistic regression). get_regression_summaries() returns a glm-shaped summary (mse, rmse, deviance, null_deviance, aic, bic, log_lik, df_residual, df_null, nobs) — R² columns are not included since they don’t apply to glm. get_regression_table() gains an exponentiate argument (default FALSE) for returning odds/rate ratios for log/logit-link models.
  • Internal: factor-level pretty-printing in get_regression_table() is now applied to the tidy output’s term column rather than model$coefficients names, which avoids breaking confint.glm’s profile-likelihood refits.
  • Drop redundant @docType package tag from R/moderndive.R (resolves issue #133). The "_PACKAGE" sentinel was already in place, so the moderndive-package alias is generated correctly.
  • Fix pennies_resamples so the replicate column is correctly numbered 1..35 instead of being uniformly 1 (resolves issue #130). The bug was an ungroup() missing in the data-raw/process_data_sets.R pipeline, so mutate(replicate = 1:n()) ran per-group on a single-row nested tibble. The dataset has been regenerated; row count and structure are otherwise unchanged.
  • New View() wrapper (resolves issue #99). In an interactive R session it behaves identically to utils::View(). In non-interactive contexts (R Markdown, Quarto, scripts) where utils::View() typically errors, it instead renders an interactive DT::datatable() inline so documents can still knit/render. DT is now in Imports. A short packageStartupMessage() is emitted only on non-interactive attach to explain the override; interactive sessions see no extra message. Attaching moderndive masks utils::View. For large data frames the inline DT::datatable() is slow and warns that the data is too big for a client-side table, so in non-interactive contexts View() now shows a random sample of n rows (default 1000) when x is larger, emitting a message that says so. New arguments n (sample size), full = FALSE (set TRUE to show every row), seed (reproducible sample), and quiet = FALSE (silence the message) control this; the sample never disturbs the caller’s RNG stream, and the interactive utils::View() path is unchanged.
  • Documentation examples now use moderndive datasets instead of base R / ggplot2 ones. View(), get_correlation(), get_regression_table(), get_regression_points(), get_regression_summaries(), plot_3d_regression(), and the package-level overview now use un_member_states_2024 (with life_expectancy_2022 ~ gdp_per_capita-style models). geom_categorical_model() now uses evals (score ~ rank) instead of ggplot2::mpg (hwy ~ drv).
  • _pkgdown.yml: site url: now includes the https:// scheme so pkgdown::check_pkgdown() matches it against the URL listed in DESCRIPTION.
  • README: added descriptive alt text to the hex-sticker image.
  • get_correlation() now accepts multiple right-hand-side variables in the formula (e.g. mpg ~ hp + cyl + wt) (resolves issue #29). The default output is a long tibble with one row per predictor; pass wide = TRUE for one column per predictor. Single-RHS behavior is unchanged. A one-time message points users to corrr::correlate() if they want a full pairwise correlation matrix; suppress it with quiet = TRUE.
  • New plot_3d_regression() function for interactive 3D scatterplots with a fitted regression plane (resolves issue #27). Pass a formula z ~ x + y and the function returns a [plotly][plotly::plotly] htmlwidget. plotly is in Suggests; install it with install.packages("plotly") to use this function.
