plot_comparison_heatmap: 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"
)

Value

A ggplot2 object.

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".

Examples

if (FALSE) {
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")
}
