Changes in version 0.1.1 (2026-11-04) - Added NEWS.md, CONTRIBUTING.md, and a support section in the README. - Added a GitHub Actions workflow that runs R CMD check on Linux, macOS, and Windows. - Added tests for the F2 calculation, input validation, and the bootstrap options. - Removed the benchmark_f2() timing helper from the package. - Changed the license from MIT to GPL-2, because parts of the code are adapted from vegan. - During development, the package was checked independently on Windows 11 (R 4.6.1) and Ubuntu 26.04 LTS (R 4.6.0), and passed. Changes in version 0.1.0 - First tagged release. - F2_adonis2() runs PERMANOVA with the F2 statistic (Anderson et al. 2017), for comparing groups when dispersions differ and group sizes are unequal. - p-values by permutation, separate-sample bootstrap, or bias-adjusted bootstrap. - Plot of the permutation null distribution. - Includes the Norway benthic macrofauna and PKD urinary metabolomics datasets, and two vignettes. - The dispersion calculation is much faster than in earlier development versions, with matching results. - Groups with fewer than two observations now give a clear error.
