Apply Color Palette to Network

Apply a color palette for node and/or edge coloring.

Usage

sn_palette(network, palette, target = "nodes", by = NULL)

Arguments

network

A cograph_network object, matrix, data.frame, or igraph object. Matrices and other inputs are auto-converted.

palette

Palette name (see list_palettes) or a function that takes n and returns n colors.

target

What to apply the palette to: "nodes" (default), "edges", or "both". For edges, the first two palette colors become the colors of positive and negative edges.

by

Name of a node-table column whose values are mapped to palette colors. When by is NULL or not a column of the node table, every node gets the first palette color.

Value

The cograph_network with the node fill colors and edge colors stored in its node_aes and edge_aes elements.
