ropensci/fellingdater: fellingdater v1.2.0

Adding new functionalities.

NEW FEATURES A new set of functions for tree-ring dating, analysis, and visualization (trs_*)

• Data generation and preparation: trs_pseudo_rwl(): Generate synthetic tree-ring datasets for testing and method development trs_select(): Select specific series from tree-ring data trs_remove(): Remove series from tree-ring datasets trs_trim(): Remove leading and trailing NA's in tree-ring datasets or single series

• Crossdating analysis: trs_crossdate(): Comprehensive crossdating analysis with multiple statistical measures trs_date_end(): Set end dates for tree-ring series based on crossdating results trs_tho(): Calculate t-values according to the Hollstein (1980) transformation trs_tbp(): Calculate t-values according to the Baillie & Pilcher (1973) transformation trs_pv(): Calculate percentage of parallel variation including SGC, SSGC, and Gleichläufigkeit, with significance levels trs_tSt(): Calculate correlation measures (Pearson r and t-values)

• Visualization: trs_plot_dated(): Display crossdating results with highlighting of parallel variation trs_plot_rwl(): Plot individual tree-ring series with customizable colors and styling

Enhanced workflow integration: Tree-ring analysis functions now seamlessly integrate with existing felling date estimation (sw_* functions) Complete dendroarchaeological workflow from data processing through crossdating to felling date estimation Support for both synthetic data generation and real dendrochronological datasets

NEW DATASET

• Weitz_2025: New sapwood model for the Brussels region (Belgium) based on Weitz et al. (2025)
