aggregateVertices: Aggregate vertices of a graph

In MiloMonnier/supplynet: Supply network design and robustness assessment tools

Description

Aggregate vertices of an igraph object. For vertices numeric columns, mean of groups is computed. For character class columns, uniques values are pasted.

Usage

aggregateVertices(g, by, v.agg = V(g))

Arguments

g	An igraph object
by	Vector of the same length than vertices to aggregate them.
v.agg	igraph.vs or character; the vertices to aggregate. Default is all graph vertices.

Value

An igraph object.

Examples

library(igraph)
g = erdos.renyi.game(100, 120, 'gnm')
plot(g)
by = sample(letters[1:10], length(V(g)), replace=TRUE)
g2 = aggregateVertices(g, by)
plot(g2)
