Changes in version 0.1.2 (2026-05-01)                  

  - Added pairwise_calculator() to compute all head-to-head comparisons
    from ranked preference data, returning a "pairwise" S3 object with
    TCP ratios, raw win counts, and Condorcet winner/loser detection.
  - Added pairwise_heatmap() to visualise pairwise results as a
    red–green diverging heatmap, with tile annotations for TCP
    percentages or raw vote counts.
  - Added dop_bar() to plot the preference distribution for a single
    contest round as a bar chart, supporting both wide and long input
    formats.
  - get_tern_data() split into get_tern_data2d() (2D plots) and
    get_tern_datahd() (HD plots).
  - get_tern_datahd() now returns the full data frame with a labels
    column, replacing the need for get_tern_labels().
  - get_tern_labels() is deprecated; use
    get_tern_datahd(ternable)[["labels"]] instead.

                 Changes in version 0.1.1 (2026-04-13)                  

  - Fixed helmert_transform() to use geozoo::f_helmert() correctly.
  - Updated package description to reflect expanded scope.
  - Addressed CRAN reviewer comments: improved documentation and
    examples across multiple functions, added data.R documentation for
    bundled datasets, removed internal sysdata.rda.

                        Changes in version 0.1.0                        

  - First release.
