prefviz 0.1.2

  • 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.
