fellingdater: Tree-ring dating and estimating felling dates of historical timbers

fellingdater provides a comprehensive suite of functions for dendrochronological and dendroarchaeological analysis, covering a workflow from tree-ring **data processing** and **crossdating**, up to the estimation and reporting of **felling dates**. Originally designed to assist dendrochronologists in inferring felling dates from dated tree-ring series with partially preserved sapwood, the package has been expanded to include a workflow for tree-ring dating, analysis, and visualization.
