EdgelistFill: Ensure an edgelist has all dyads and a column of weights.

Description

Given a matrix or data.frame edgelist, fill in all possible edges not already listed with a weight of 0 or the value of fillBlanksWith.

Usage

EdgelistFill(elist, fillBlanksWith = 0, nodelist)

Arguments

elist

data.frame or matrix, see 'Details' for formatting assumptions.

fillBlanksWith

numeric, default weight for edges not already listed in elist.

nodelist

character, optional list of node names.

Value

data.frame, full list of all possible edges with weights for each in third column.

Details

The elist can be either a data.frame or a matrix with either 2 or 3 columns. Each row is an edge. The first column lists the node the edge is 'from' and the second column lists the node the edge is 'to'. If there is a third column, it lists the weight of the edge.

Examples

g <- erdos.renyi.game(10, 2/10)
EdgelistFill(get.edgelist(g))
EdgelistFill(get.edgelist(g), nodelist=1:10)

E(g)$weight <- runif(ecount(g))
el <- cbind(get.edgelist(g), E(g)$weight)
EdgelistFill(el)
EdgelistFill(el, nodelist=1:10)
