Description: Provides tools for constructing, computing, and using distance
    measures for numerical, categorical, and mixed-type data. The package
    implements a flexible framework in which continuous and categorical
    components can be combined under additive, commensurable, and
    association-aware specifications. Supported methods include classical
    distances such as Gower, Euclidean, Manhattan, and Mahalanobis-type
    distances; categorical dissimilarities such as simple matching,
    occurrence-frequency, and association-based measures; and mixed-type
    presets designed to reduce biases due to variable type, scale,
    distribution, redundancy, and number of categories. The package also
    provides scaling options, supervised and unsupervised distance
    constructions, leave-one-variable-out tools for distance-based variable
    importance, and integration with distance-based learning workflows such
    as nearest-neighbour prediction, partitioning around medoids, and
    spectral clustering. Methods are motivated by van de Velden,
    Iodice D'Enza, Markos, and Cavicchia (2026)
    <doi:10.1080/10618600.2026.2680181> and related work on categorical
    and mixed-type dissimilarities.
