Plot Pattern Causality Matrix

Creates a heatmap visualization of the pattern causality matrix for positive, negative, or dark causality relationships. This function generates a heatmap using ggplot2 to visualize the specified causality matrix.

Usage

# S3 method for class 'pc_matrix'
plot(
  x,
  status,
  width = 0.85,
  height = 0.75,
  radius = grid::unit(3, "pt"),
  alpha = 0.53,
  show_text = FALSE,
  show_legend_title = FALSE,
  ...
)

Arguments

x

A pc_matrix object containing causality matrices.

status

The type of causality to plot ("positive", "negative", or "dark").

width

Numeric value specifying the width of the bars (default: 0.85).

height

Numeric value specifying the height of the bars (default: 0.75).

radius

Grid unit specifying the corner radius of the bars.

alpha

Numeric value specifying the transparency (default: 0.53).

show_text

Logical, whether to show numerical values on the plot.

show_legend_title

Logical, whether to display the legend title.

...

Additional arguments passed to plotting functions.

Value

A ggplot object invisibly.
