fellingdater 1.2.0 (2025-06-30)
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)
fellingdater 1.1.0 (2025-06-05)
- Fixes to ensure that a user-defined sapwood dataset can be used with all relevant functions (fd_report(), sw_combine() and sw_sum().
- Extra checks on the input (e.g. check_input(), check_duplicate_labels() and check_sapwood_data_user(). These additional functions have been added to ‘helper-functions.R’ and integrated into fd_report(), sw_combine() and sw_sum().
- The example data sets for testing sw_combine() and sw_sum() and fd_report() have been renamed from trs_example(1 to 7) to sw_example(1 to 7).
