testflow 0.8.2 (2026-07-02)

Outlier workflow

• Standardized test_outliers() on the same test_*(formula, data, ...) calling convention used by the other workflow helpers.
• Kept outlier visualization on the generic plot() S3 path via plot.testflow().
• Hardened assumption printing so workflows with extra diagnostic columns no longer break print().

Output

• Structured printed testflow and summary output with cli-based colors, section headings, field labels, and assumption bullets.
• Interactive console colors are enabled by default for printed testflow objects and summaries. Set options(testflow.cli_colors = FALSE) to disable them, or options(testflow.cli_colors = TRUE) to force colors in scripts.

Documentation and release prep

• Added a dedicated sumtab() example to the README.
• Added an effect-size formulas vignette documenting the implemented formulas for Cohen's d, eta squared, Cramer's V, rank-biserial correlation, Kendall's W, and related workflow summaries.
• Added validation tests that pin the documented Cohen's d formulas to the implementation.
• Removed generated vignette PDFs from the source repository.

testflow 0.8.1

Summary tables

• Added sumtab() for formula-driven descriptive summary tables with optional automatic p-value selection.

Validation and documentation

• Added canonical references to workflow documentation and the main vignette.
• Added deeper validation checks against base R/reference calculations for one-sample tests, proportions, correlations, categorical association, and factorial ANOVA.
• Kept the hardened repeated-measures and post-hoc workflows from 0.8.0.

testflow 0.8.0

Method hardening

• Replaced the repeated-categorical Friedman approximation with an explicit Cochran Q implementation for binary repeated measures.
• Added pairwise McNemar post-hoc comparisons for repeated categorical workflows.
• Added base R repeated-measures ANOVA extraction for normal repeated numeric workflows.
• Added paired post-hoc comparisons for repeated numeric workflows: paired t-tests after repeated-measures ANOVA and paired Wilcoxon tests after Friedman.
• Added method-specific post-hoc selection for multi-group comparisons: Tukey HSD after classical ANOVA, Welch pairwise t-tests after Welch ANOVA, and pairwise Wilcoxon tests after Kruskal-Wallis.
• Added validation tests comparing repeated ANOVA and Cochran Q results against explicit base R/reference formulas.

testflow 0.7.0

First public release.

Workflow API

• Added formula-first support for core study designs:
  • test_two_groups(outcome ~ group, data = data)
  • test_groups(outcome ~ group, data = data)
  • test_categorical(x ~ y, data = data)
  • test_correlation(y ~ x, data = data)
  • test_paired(after ~ before, data = data)
  • test_factorial(outcome ~ factor1 * factor2, data = data)
• Preserved data-first and pipe-friendly calls for existing examples.

Results

• Primary test results now expose the null hypothesis, confidence interval columns when available, and effect size fields.
• as_tibble() includes H0, confidence interval, effect size name, effect size estimate, effect size magnitude, and decision.

Documentation

• Added rendered HTML vignettes in inst/doc.
• Expanded the README with a list of implemented workflows and tests considered.

Quality

• Added focused tests for formula-first calls, H0, confidence intervals, and effect size exposure.
• Added GitHub Actions R CMD check workflow.
