Description: A program for reconstructing local fire histories from
    high-resolution, continuously sampled lake-sediment charcoal records.
    'CharAnalysis' decomposes a charcoal record into low- and high-frequency
    components and uses locally defined thresholds to separate fire signal
    from noise, following the approach of Higuera et al. (2009)
    <doi:10.1890/07-2019.1>, with underlying assumptions and rationale
    described in Higuera et al. (2010) <doi:10.1071/WF09134>. The package is
    designed for macroscopic charcoal records with contiguous sampling fine
    enough to resolve individual fire events, and is not appropriate for
    low-resolution or discontinuously sampled records. See the package URL
    for the User's Guide and application examples.
