Convert A Network to an Integer Edgelist

This function converts a character string edgelist into an integer edgelist.

integer.edgelist(network)

Arguments

network	An edge list, which is a matrix or data frame with 2 or 3 columns. The first 2 columns contain the nodes that interact with each other, which can be character strings or integer values. The optional third column is a numerical vector of weights for each edge, which is stripped from the output.

A list containing the following components:

edges

A matrix with two columns containing the integer edgelist.

nodes

A named integer vector mapping node integer IDs to their character string equivalents.

## Generate graph and convert into an integer edgelist.
g <- data.frame(letters[1:10],letters[6:15])
gi <- integer.edgelist(g)
