Extracting Signals from Wavelet Spectra.

WaverideR

WaverideR is an R package for advanced cyclostratigraphic analysis of stratigraphic data sets. It provides a comprehensive suite of spectral tools for detecting, visualising, and tracking non-stationary astronomical cycles, including continuous wavelet transforms (CWT), the superlet transform, windowed FFT, and evolutionary harmonic analysis (EHA) (wrapper). These methods allow both manual and automated tracking of orbital cycles in spectra and scalograms, even in records affected by large changes in sedimentation rate.Building on this spectral framework, WaverideR supports multi-proxy integration and Monte Carlo–based uncertainty propagation to construct statistically robust floating and absolute astrochronological age models. The package includes dedicated tools to quantify analytical wavelet uncertainty, estimate the duration of stratigraphic gaps and hiatuses, and integrate external radioisotopic age constraints. Designed for complex and incomplete stratigraphic records, WaverideR enables investigation of the imprint of astronomical forcing even in suboptimal datasets.
