 Pearson correlation isn't designed for binary data (i.e., True/False or 0/1) so you can use `MCC` instead.

 Let's engineer some categories by collapsing by some predefined category. Check out `Phylogenomic Functional Categories` in [Espinoza et al. 2022](https://academic.oup.com/pnasnexus/article/1/5/pgac239/6762943) for how these are used in practice.
