sg2igraph {SpatialGraph}

Map a SpatialGraph into an igraph

Description

The vertex and edge information in a SpatialGraph is mapped into an igraph object

Usage

sg2igraph(sg, directed=FALSE)

Arguments

sg

SpatialGraph

directed

whether the resulting igraph is directed

Details

It is assumed that the SpatialGraph, used as input, is correct (i.e.g all records in sg@e@data have the two first field correctly identifying the field 'ID' in sg@v. It is also assumed that the sg@e@data data.frame has the fields div and len. These two are highly useful to conduct network operations on the resulting igraph

Value

An igraph
