CharAnalysis: Peak Detection and Fire History from Sediment-Charcoal Records
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.
