hilldiv3 unifies neutral, phylogenetic, and functional Hill-number diversity analysis in R, supporting all twelve benchmarked operation–type combinations and building pairwise (dis)similarity matrices 15–820× faster than hilldiv2 and hillR.
- Why it matters: Existing Hill-number workflows require combining multiple R packages with incompatible conventions, making consistent measurement, partitioning, and (dis)similarity comparisons across diversity types difficult.
- What they did: The hilldiv3 package implements per-sample diversity, nested multiplicative partitioning across scales, bounded (dis)similarities and pairwise matrices, diversity profiles, evenness, redundancy, and allocation of Hill power sums to taxa or sets.
- The result: In Microflora Danica (360 samples, 5,518 genomes, eight habitats), neutral, phylogenetic, and functional diversity turnover differed by habitat, and a near-constant Actinomycetota share masked opposing shifts, enabling directly comparable results from one Hill-number formulation.
