aridagri: An R package for comprehensive statistical analysis of agricultural field experiments

The aridagri package provides a unified R framework for comprehensive statistical analysis of agricultural field experiments. It implements analysis of variance (ANOVA) for 16 experimental designs, including all split-plot variations with appropriate error terms, seven post-hoc comparison tests with letter groupings, seven stability analysis methods with integrated genotype ranking, thermal indices, crop growth analysis, path analysis, and structural equation modelling. All 33 exported functions produce publication-ready output with standard error (SE), critical difference (CD), and coefficient of variation (CV). A unified verbose parameter enables interactive and programmatic use. The package is distributed under GPL-3 and available from CRAN and GitHub.
