Summary of Changes

Hello @strengejacke, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the parameters package by integrating equivalence_test() functionality with key output objects from the modelbased package. This allows users to perform equivalence tests directly on estimated means, contrasts, and slopes, streamlining statistical workflows. Additionally, the update includes a minor version bump and minor documentation improvements for example code blocks.

Highlights

• Extended Equivalence Testing: The equivalence_test() function now supports objects generated by the modelbased package, specifically estimate_means, estimate_contrasts, and estimate_slopes, enhancing interoperability.
• Improved ROPE Range Handling: The internal .check_rope_range function has been updated to correctly extract the underlying model from modelbased-objects to define the Region of Practical Equivalence (ROPE).
• Documentation and Version Updates: The package version has been incremented to 0.28.2.2, RoxygenNote updated, and minor cleanups were applied to example code in several documentation files for better R version compatibility.

Code Review

This pull request adds support for equivalence_test() for objects from the modelbased package, specifically for estimate_means, estimate_contrasts, and estimate_slopes classes. This is achieved by aliasing the existing equivalence_test.lm method and adding special handling within the .check_rope_range() helper function to correctly determine the ROPE range from the underlying model. The implementation is sound. I have one suggestion to improve user feedback when the underlying model cannot be extracted. The pull request also includes documentation updates across many files, which appear to be related to a roxygen2 version update and are consistent.
