s20x 3.2.276

Data

• Store nzarrivals.df$month as a factor with levels ordered by month.abb and update the dataset documentation accordingly.

s20x 3.2.274

Data

• Add nzarrivals.df, a monthly Stats NZ Infoshare arrivals data set, and fix the Stage 14 colors() import so note-level checks remain strict.

s20x 3.2.273

• Document remaining Stage 14 internal helper functions with roxygen2 comments.

s20x 3.2.272

• Document internal prediction helper functions with roxygen2 comments.

s20x 3.2.271

Modernisation

• Removed qualified namespace calls from R source files by adding roxygen imports, broadened internal helper documentation, and hardened the Stage 14 style-compliance regression test.

s20x 3.2.270

Modernisation

• Consolidated residual and fitted-value extraction for targeted diagnostic plotting internals without changing plotting output or public APIs.

s20x 3.2.269

Modernisation

• Added a small internal graphics-parameter save/restore helper and used it in targeted diagnostic plotting code paths without changing plotting output.

s20x 3.2.268

Modernisation

• Deprecated legacy diagnostic plotting helpers modelcheck(), modcheck(), boxqq(), stripqq(), and the autocor.plot() alias, and removed them from the exported API while keeping their internal compatibility definitions.

s20x 3.2.267

Modernisation

• Added prediction-wrapper regression coverage for multi-row return shapes, binomial-logit predictGLM() output, and wrapper-level quasi interval multiplier behaviour without changing prediction internals.

s20x 3.2.264

Modernisation

• Standardised predictGLM() return shape to a data frame with stable fit, lwr, and upr columns, while preserving link/response scale calculations and legacy fallback to link-scale output for unsupported type values.

s20x 3.2.263

Modernisation

• Consolidated internal prediction interval output formatting for linear-model and GLM teaching wrappers while preserving legacy return shapes, column names, rounding, and scale handling.

s20x 3.2.262

Modernisation

• Consolidated prediction-wrapper newdata data-frame validation into a shared internal helper and removed duplicated validation from predictGLM() without changing prediction output or error text.

s20x 3.2.261

Modernisation

• Added the Stage 13 prediction-wrapper internal audit note, identifying narrow maintenance targets for prediction internals while deferring public API and behaviour changes.

s20x 3.2.260

Modernisation

• Finalised the Stage 12 documentation-coherence developer note, summarising completed documentation improvements and deferring deeper API or behavioural refactors to later stages.

s20x 3.2.259

Modernisation

• Audited exported help examples for strict-check suitability, confirmed remaining synthetic examples are deterministic or guarded, and tightened freq1way() documentation wording without changing behaviour.

s20x 3.2.258

Modernisation

• Standardised diagnostic help wording for model checking, residuals versus fitted values, Q-Q plots, and plotting side effects without changing package behaviour.

s20x 3.2.257

Modernisation

• Guarded the displayPairs() help example so it only runs the optional emmeans workflow when emmeans is available, keeping examples suitable for strict checks without changing package behaviour.

s20x 3.2.256

Modernisation

• Clarified prediction helper and AR-error model documentation so teaching wrappers are distinguished from ordinary predict() and independent-error ANOVA behaviour without changing package behaviour.

s20x 3.2.255

Modernisation

• Replaced the artificial summary1way() help example with computer.df, made the summaryStats() matrix example dataset-based, and tightened summary-helper documentation wording without changing behaviour.

s20x 3.2.254

Modernisation

• Applied a strict NZ English and grammar documentation pass and accepted "normalised" as a package-owned alias for "normalized" residual diagnostics while preserving compatibility.

s20x 3.2.253

Modernisation

• Made diagnostic helper examples deterministic or dataset-based and corrected small documentation spelling and grammar issues without changing diagnostic behaviour.

s20x 3.2.252

Modernisation

• Replaced the interactionPlots() help examples with the arousal.df teaching dataset and clarified the deprecated vector-form example wording without changing plotting behaviour.

s20x 3.2.251

Modernisation

• Added a Stage 12 documentation audit covering help examples, teaching datasets, time-series examples, R CMD check suitability, and NZ English spelling and grammar notes without changing package behaviour.

s20x 3.2.250

Modernisation

• Added a Stage 11 completion plan summarising completed API-consistency work and deferring larger documentation and internal refactor items to later stages.

s20x 3.2.249

Modernisation

• Documented diagnostic plotting helper return conventions and added regression tests for current validation behaviour without changing plotting behaviour.

s20x 3.2.248

Modernisation

• Documented and tested crosstabs() and rowdistr() printed-output and invisible-return conventions without changing behaviour.

s20x 3.2.247

Modernisation

s20x 3.2.246

Modernisation

• Documented and tested summary1way() printed-output and invisible-return conventions without changing behaviour.

s20x 3.2.245

Modernisation

• Documented and tested summaryStats() printed-output and invisible-return conventions without changing behaviour.

Modernisation

• Added a Stage 11 return-convention modernisation plan to guide future low-risk API updates without changing public behaviour.

s20x 3.2.243

Modernisation

• Added a Stage 11 audit of printed-output and invisible-return conventions without changing public behaviour.
