heatmap_network: Plot heatmap representation of a network

In tgrimes/SeqNet: Generate RNA-Seq Data from Gene-Gene Association Networks

Description

This function plots the given network as a heatmap to visualize its connections. If the network is weighted, then the heatmap will use greyscale colors to represent connection strengths; black squares correspond to the strongest connections, while lighter color squares are weaker connections.

Usage

heatmap_network(network, main = NULL,
  col = colorRampPalette(RColorBrewer::brewer.pal(8, "Greys"))(50), ...)

Arguments

network	Either a network object or association matrix of the network.
main	A string containing the title for the graph.
col	Color palatte used for heatmap. See ?heatmap for details.
...	Additional arguments passed to 'heatmap()'.

Value

The matrix used to create the heatmap

Examples

set.seed(12345)
nw <- random_network(10)
nw <- set_node_names(nw, paste("node", 1:10, sep = "_"))
heatmap_network(nw, "Unweighted Network")
nw <- gen_partial_correlations(nw)
heatmap_network(nw, "Weighted Network")
