%description
Provides a unified interface for computing, comparing, and examining
distances, dissimilarities, divergences, and selected similarities for
bioinformatics data. The core installation exposes 60 canonical named
routes for numerical data and more than 90 when the suggested
'philentropy' backend is installed; aliases, user-defined functions, and
mixed-data combinations are not included in these counts. Weighted
Minkowski distances can be computed through 'parallelDist', an internal
multicore implementation, or optional 'OpenCL' kernels, while the
established weighted Euclidean GPU implementation is retained as the
optimized p = 2 route. The package also supports theory-guided comparison
of distance distributions for clustering, explicit mathematical property
classifications, mixed-data constructions through 'manydist', and a
specialized Gene Ontology-derived TF-IDF distance.
