Term co-occurrence heatmap

Tile heatmap of pairwise within-response term co-occurrence counts for a co_occurrence result. The result's edge list (term_a, term_b, n) is pivoted into a full symmetric term-by-term grid before plotting, so each pair's tile appears twice, once on either side of the diagonal, the way the other tile heatmaps in this file (sframe_plot_correlation_matrix(), sframe_plot_efa_loadings()) read as a full grid rather than a triangle.

Usage

sframe_plot_cooccurrence(result, palette = c("web", "print"))

Arguments

result

A co_occurrence result list from run_analysis_plan().

palette

One of "web" or "print". See sframe_brand().

Value

A ggplot2 object, or NULL when the result carries no table.

Examples

# \donttest{
if (requireNamespace("ggplot2", quietly = TRUE)) {
  demo <- sframe_demo("open_text")
  res <- run_analysis_plan(demo$responses, demo$instrument)
  sframe_plot_cooccurrence(res$RQ4)
}
