leafwax: Bayesian Inversion of Leaf Wax Hydrogen Isotopes to Precipitation

Bayesian inversion of leaf wax hydrogen isotopes to reconstruct precipitation isotopes using hierarchical spatial models. Provides fourteen Bayesian models that vary in their use of spatial Gaussian processes and ancillary covariates (precipitation amount, plant functional type, C4 fraction). Models are pre-computed using 'Stan' and stored as posterior distributions, so prediction does not require 'Stan' to be installed. A 100-draw fixture ships with the package; full 1000-draw posteriors are downloaded from a versioned 'Zenodo' deposit on first use; see Bradley (2026) <doi:10.5281/zenodo.20085465>.
