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

fellingdater - fellingdater v1.1.0

• Minor fixes to ensure that a user-defined sawpood 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 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).
