In cograph: Analysis and Visualization of Complex Networks

Plot Comparison Heatmap

Description

Creates a heatmap visualization comparing two networks.

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, CographNetwork, tna, or igraph object.
y	Second network: same type as x. NULL to plot just x.
type	What to display: "difference" (x - y), "x", or "y".
name_x	Label for first network in title. Default "x".
name_y	Label for second network in title. Default "y".
low_color	Color for low/negative values. Default "blue".
mid_color	Color for zero/middle values. Default "white".
high_color	Color for high/positive values. Default "red".
limits	Color scale limits. NULL for auto. Use c(-1, 1) for normalized.
show_values	Logical: display values in cells? Default FALSE.
value_size	Text size for cell values. Default 3.
digits	Decimal places for cell values. Default 2.
title	Plot title. NULL for auto-generated.
xlab	X-axis label. Default "Target".
ylab	Y-axis label. Default "Source".

Value

A ggplot2 object.

Examples

## Not run: 
set.seed(42)
m1 <- matrix(runif(25), 5, 5)
m2 <- matrix(runif(25), 5, 5)
rownames(m1) <- colnames(m1) <- LETTERS[1:5]
rownames(m2) <- colnames(m2) <- LETTERS[1:5]

# Difference heatmap
plot_comparison_heatmap(m1, m2)

# Show just one network
plot_comparison_heatmap(m1, type = "x")

## End(Not run)
