Description: Implements the Stratigraphic Plug Alignment (SPA)
        procedure for integrating sparsely sampled plug-based
        measurements (e.g., total organic carbon, porosity, mineralogy)
        with high-resolution X-ray fluorescence (XRF) geochemical data.
        SPA uses linear interpolation via the base approx() function
        with constrained extrapolation (rule = 1) to preserve
        stratigraphic order and avoid estimation beyond observed
        depths. The method aligns all datasets to a common depth grid,
        enabling high-resolution multivariate analysis and
        stratigraphic interpretation of core-based datasets such as
        those from the Utica and Point Pleasant formations. See R Core
