Plot the pairwise nesting index matrix

Renders the directed nesting index \(1 - H(B \mid A)/H(B)\) as a heatmap between facet pairs, highlighting fully nested relationships close to 1. Colour scale runs from 0 (crossed, white / cold) to 1 (fully nested, dark).

Usage

# S3 method for class 'mfrm_facet_nesting'
plot(
  x,
  preset = c("standard", "publication", "compact", "monochrome"),
  draw = TRUE,
  ...
)

Arguments

x

An mfrm_facet_nesting object.

preset

Plot preset.

draw

Logical; print the ggplot figure when TRUE.

...

Reserved.

Value

Invisibly, a ggplot object. plot_data() extracts the rendered nesting matrix and pairwise summary table.

Session plot defaults

See mfrmr_visual_diagnostics for options(mfrmr.plot_preset), argument precedence, and appearance when saving or reusing a plot.
