Heatmap of pairwise results

Source: R/quick_plots.R
pairwise_heatmap.Rd

Plots a full N×N heatmap of pairwise results from a pairwise_calculator() object. Each cell shows how the row item performed against the column item. Color always encodes the TCP ratio (green = win, red = lose, white = 50/50).

Usage

pairwise_heatmap(x, value = c("tcp", "count"))

Arguments

x

A pairwise object returned by pairwise_calculator().

value

"tcp" (default) or "count". Controls the tile annotation:

  • "tcp": shows the TCP percentage, e.g. "56.8%".

  • "count": shows the raw vote count, e.g. "2841".

Value

A ggplot object.

See also

pairwise_calculator() to compute the input object.

Examples

library(prefio)

prefs <- data.frame(
  A = c(1, 1, 1, 2, 2),
  B = c(2, 2, 3, 1, 3),
  C = c(3, 3, 2, 3, 1)
) |>
  wide_preferences(col = vote, ranking_cols = A:C)

result <- pairwise_calculator(prefs, preferences_col = vote)
pairwise_heatmap(result, value = "tcp")

pairwise_heatmap(result, value = "count")
