analyze.graph.measures.igraph: Analyzing graph measures of an igraph object

In comato: Analysis of Concept Maps and Concept Landscapes

Description

analyze.graph.measures.igraph is a convenience method that can be called directly on the result of landscape. It works just like analyze.graph.measures.conceptmap

Usage

## S3 method for class 'igraph'
analyze.graph.measures(x)

Arguments

x	An igraph object.

Value

A list with named components that contain the betweenness measure, the edge.connectivity, the diameter, the degree distribution and the communities using the Fastgreedy algorithm.

Examples

require("igraph")
g1 = set.vertex.attribute(erdos.renyi.game(15, 0.7, type="gnp"), "name", value=1:15)
analyze.graph.measures(g1)

Example output

1: In rgl.init(initValue, onlyNULL) : RGL: unable to open X11 display
2: 'rgl_init' failed, running with rgl.useNULL = TRUE 
3: .onUnload failed in unloadNamespace() for 'rgl', details:
