Description: Provides a framework for quality-aware analysis of
        ground-based phenological data from the PEP725 Pan-European
        Phenology Database (Templ et al. (2018)
        <doi:10.1007/s00484-018-1512-8>; Templ et al. (2026)
        <doi:10.1111/nph.70869>) and similar observation networks.
        Implements station-level data quality grading, outlier
        detection, phenological normals (climate baselines), anomaly
        detection, elevation and latitude gradient estimation with
        robust regression, spatial synchrony quantification, partial
        least squares (PLS) regression for identifying
        temperature-sensitive periods, and sequential Mann-Kendall
        trend analysis. Supports data import from PEP725 files,
        conversion of user-supplied data, and downloadable synthetic
        datasets for teaching without barriers of registration. All
        analysis outputs provide 'print', 'summary', and 'plot'
        methods. Interactive spatial visualization is available via
        'leaflet'.
