Description

A function to produce an “igraph” object with the “nodelist” and “edgelist”, which could be returned by the function readshpnw.

Usage

nodedge_list2igraph(
  nodelist,
  edgelist,
  weight = NULL,
  eadf = NULL,
  Directed = FALSE
)

Arguments

nodelist	A “nodelist” object
edgelist	An “edgelist” object
weight	A numberic vector to weight all the edges in the “edgelist”, of which the length equals to the number of edges;
eadf	A data frame of attributes corresponding to all the edges;
Directed	TRUE if edges are directed, FALSE otherwise;

Value

1. The weighting vector, “weight”, will be used as default for any weigted calculations with edges in the “igraph” object. 2. The coordinate of each node is attached as attributes “X” and “Y”, which could be retrived via the function “get.vertex.attribute” from the package igraph.
