In MRS: Multi-Resolution Scanning for Cross-Sample and Cross-Group Differences

MRS 1.3.2

• Standardized reproducibility seeds across examples, demos, tests, and archived simulation scripts to 12345.
• Consolidated the former standalone examples into three non-redundant, reproducible visual demos. They cover one-dimensional Bayesian FDR, observed-versus-shuffled two-dimensional scans, pooled versus replicate-aware fitting across small, medium, and large replicate counts, both ANDOVA integration methods, baseline effects, and representative multiresolution trees.
• Restored current CRAN metadata and registered all native routines.
• Replaced deprecated Armadillo index-returning max() calls and fixed an uninitialized-variable path in the C++ tree traversal.
• Added input validation that prevents invalid dimensions, labels, bounds, and tuning parameters from reaching the C++ core.
• Restored the version 1.2.6 ANDOVA midpoint-quadrature default; deterministic and randomized compatibility suites now reproduce legacy numerical and tree results.
• Preserved the legacy default sample-space bounds for ordinary data while safely supporting constant and non-positive dimensions.
• Documented posterior sampling, effect-size baselines, numerical integration, and Bayesian-FDR plotting introduced on the development branch.
• Fixed posterior sample matrix shaping and direction probabilities, multidimensional sampling, sampling without a representative tree, Bayesian-FDR matrix indexing, and a Riemann-quadrature second-moment error.
• Kept sampled ANDOVA probabilities inside their valid domain and removed undefined behavior in dyadic bin conversion and region reconstruction.
• Added numerical compatibility, posterior-sampling, invariant, validation, plotting, and native-routine regression tests.
• Removed the unused optimx dependency and replaced the igraph-backed representative-tree renderer with a deterministic base-graphics renderer.
• Added explicit return-value documentation for all exported plotting and print methods, including the meaning of their graphical or printed side effects.
