Plot Comparison Heatmap — plot_comparison

Plots a heatmap of the difference between two weight matrices, or of either matrix alone. Rows are source nodes and columns are target nodes.

Usage

plot_comparison_heatmap(
  x,
  y = NULL,
  type = c("difference", "x", "y"),
  name_x = "x",
  name_y = "y",
  low_color = "blue",
  mid_color = "white",
  high_color = "red",
  limits = NULL,
  show_values = FALSE,
  value_size = 3,
  digits = 2,
  title = NULL,
  xlab = "Target",
  ylab = "Source"
)

Arguments

x: First network: matrix, cograph_network, tna, igraph, or list with a matrix weights component.
y: Second network, of the same type and dimensions as x. Required for type = "difference" and type = "y"; it may be NULL for type = "x".
type: What to display: "difference" (x - y), "x", or "y".
name_x: Label for the first network in the default title.
name_y: Label for the second network in the default title.
low_color: Color for low (negative) values.
mid_color: Color for zero.
high_color: Color for high (positive) values.
limits: Color scale limits. NULL uses the data range. Use c(-1, 1) for normalized values.
show_values: Logical. Display values in cells?
value_size: Text size for cell values.
digits: Decimal places for cell values.
title: Plot title. NULL builds one from type, name_x and name_y.
xlab: X-axis label.
ylab: Y-axis label.

Value

A ggplot object. The color scale is a diverging gradient with its midpoint at 0.
