R: Computes colors for vertices according to their attributes.
colorVertexByAttrR Documentation

Computes colors for vertices according to their attributes.

Description

This function returns a list of colors for vertices, assigned similar colors if they share a common attribute (ex: in the same pathway, etc).

Usage

colorVertexByAttr(graph, attr.name, col.palette = palette())

Arguments

graph

An annotated igraph object.

attr.name

The attribute name (ex: "pathway") by which vertices will be colored. Complex attributes, where a vertex belongs to more than one group, are supported.

col.palette

A color palette, or a palette generating function (ex:

col.palette=rainbow

).

Value

A list of colors (in HEX format) for vertices.
