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>.https://github.com/r-universe/bradleylab/actions/runs/27608842660Mon, 08 Jun 2026 02:34:58 GMTleafwax0.2.7successhttps://bradleylab.r-universe.devhttps://github.com/bradleylab/leafwaxpaleo-record-workflow.Rmdpaleo-record-workflow.htmlWhen can a leaf-wax record support a precipitation-isotope claim?2026-05-08 02:53:262026-06-01 17:49:07
