jjstatsplot 0.0.32.66 (2026-01-01)

New Features

ggpubr Integration

  • NEW: Added publication-ready plot variants using ggpubr package across multiple analyses
    • jjwithinstats: Added ggpubr plot option for within-subjects/paired data
      • Multiple plot types: boxplot, violin, paired (with connecting lines), line (mean trajectory)
      • Journal-specific color palettes: JCO, NPG, AAAS, Lancet, JAMA, NEJM
      • Options for statistical comparisons, individual trajectories, and overlay points
    • jjpiestats: Added modern donut chart variant
      • Publication-ready donut charts with journal color palettes
      • Clean, professional aesthetic for reports and publications

Enhanced Clinical Workflow Features

Ridge Plots (jjridges)

  • NEW: Clinical analysis presets with automatic configuration
    • Biomarker Distribution (nonparametric + Cliff's delta)
    • Treatment Response (violin plots + Bonferroni correction)
    • Age by Disease Stage (parametric + Cohen's d)
    • Tumor Size Comparison (Hodges-Lehmann shift)
    • Lab Values by Group (robust tests + Hedges' g)
    • Survival Time Distribution (median + quartiles)
  • Added comprehensive help panels:
    • showAboutPanel: Interpretation guidance and clinical examples
    • showAssumptions: Statistical assumptions and methodological notes
  • Enhanced statistical warnings for repeated measures/longitudinal data

Pie Charts (jjpiestats)

  • NEW: Interactive guidance panels
    • showSummary: Natural-language summary suitable for copy-paste into reports
    • showAssumptions: Detected violations and Fisher exact test recommendations
    • showInterpretation: Effect size interpretation and clinical context

Segmented Total Bar Charts (jjsegmentedtotalbar)

  • NEW: Dual plot type support
    • Traditional 100% stacked bars
    • Flerlage-style segmented total bars (Kevin Flerlage design)
      • Emphasizes both totals and composition
      • Customizable labels, colors, transparency
      • Background box styling options
  • Reorganized options for clearer workflow

Lollipop Charts

  • NEW: Data aggregation options for repeated measures
    • No aggregation (plot all points)
    • Mean, Median, Sum aggregation
    • Guidance for clinical measurements vs. counts
  • Default empty strings for labels/titles for cleaner initial plots

User Experience Improvements

  • Multiple analyses updated with improved default settings for cleaner initial plots
    • jjwithinstats: Violin and boxplot defaults changed to false for simpler initial view
    • jjpiestats: Proportion test and BF message defaults to false to reduce clutter
    • jjsegmentedtotalbar: Percentages, outlines, export_ready defaults to false
    • jwaffle: Legend default to false
  • Enhanced explanatory text across multiple analyses
  • Improved statistical assumption warnings (especially for repeated measures data)

Package Dependencies

  • Added ggpubr to Imports for publication-ready plot variants
  • Added rstatix to Imports for enhanced statistical testing support

Documentation

  • Updated R documentation for all modified analyses
  • Enhanced roxygen2 documentation with version 7.3.3
  • Improved parameter descriptions and usage examples

Bug Fixes

  • Fixed documentation formatting issues in several .Rd files

jjstatsplot 0.0.31.84 (2025-10-03)

New Features

Hull Plot Analysis

  • NEW: Added hullplot module for cluster and group visualization
    • Creates polygonal boundaries around data points grouped by categorical variables
    • Based on ggforce::geom_mark_hull() function
    • Perfect for visualizing customer segments, patient subgroups, and data clusters
    • Features include:
      • Customizable hull concavity (0-2 range)
      • Optional confidence ellipses
      • Outlier detection
      • Group statistics summary
      • Natural language interpretation
      • Multiple color palettes (default, viridis, Set1, Set2, Dark2, clinical)
      • Multiple plot themes (minimal, classic, light, dark, clinical)
      • Support for color and size variables
      • Automatic fallback to convex hulls when V8/concaveman packages unavailable

Improvements

Package Dependencies
