 OmicFlow is a generalised data structure for fast and efficient loading of various sparse omics data. It can handle metataxonomics/metagenomics data in text or [BIOM](https://biom-format.org/documentation/format_versions/biom-2.0.html) and extends to `proteomics` and other `omics` types. It also supports non-sparse data, but it's performance peaks in sparsity.

 By default PERMANOVA is applied pairwise against each group within the specified contrast, via `group_by` that is used in `pairwise_adonis`. The permutation design in `vegan::adonis2` is by default set to `free`. But this may not always be the right test when you have paired samples and you also want to restrict permutations between correlated values. Therefore, `pairwise_adonis` supports a custom permutation design, which can be constructed via [permute](https://cran.r-project.org/web/packages/permute/vignettes/permutations.html) and fed into `vegan::adonis2` as a function via `pairwise_adonis` with the flag `perm_design`.
