AgriDataTools 0.2.1 (2026-09-02)

• Comprehensive Graphical Engine Refactoring (plot_agri_graphics):

  • Fully restored and optimized all plotting modules (residual, correlation, mean, pca, cluster, and path) with zero data loss.
  • Resolved hardcoding issues, label bugs (such as G-1, G-2 naming conflicts), and color palette limitations across all visualization types.
  • Implemented dynamic text sizing (cex) and automated genotype aggregation in PCA biplots to eliminate text overlapping and ensure clean rendering for large datasets.
  • Added unconstrained dynamic color palettes in circular dendrograms to support unlimited cluster groups smoothly.
  • Configured robust graphics state safety guards (on.exit and par restoration) to prevent graphical device leaks during residual and circular cluster plotting.

• Package Infrastructure & CRAN Compliance:

  • Updated version number to 0.2.0 to reflect major functional enhancements and critical bug fixes.
  • Integrated official BugReports and GitHub repository metadata links into the DESCRIPTION file.
  • Enhanced internal error-handling and input validation routines for all analytical payloads across statistical modules.

AgriDataTools 0.1.2 (2026-08-08)

• Initial structural deployment of the core infrastructure.
• Integrated complete analytical engines for CRD and RCBD Analysis of Variance (ANOVA).
• Added multiple group comparison post-hoc matrices (LSD, Tukey, and Scheffe testing blocks).
• Integrated core statistical functions including Summary Statistics, Correlation Analysis, Path Coefficients, and Principal Component Analysis (PCA).
• Finalized multivariate clustering modules (Hierarchical Agglomerative Clustering) and multi-trait plotting systems.
