edge2Mat: Convert network edges to adjacency matrix

In paodan/funcTools: some useful function tools in practice

Convert network edges to adjacency matrix

Description

Convert network edges to adjacency matrix

Usage

edge2Mat(edge, rownm, colnm, direction = TRUE, rmName = FALSE, restValue = 0)

Arguments

edge	a data.frame of three columns, the first two columns represent nodes in a network, the third column is the weight.
rownm	row names in the final adjacency matrix. All node names must present in either rownm or colnm.
colnm	column names in the final adjacency matrix. All node names must present in either rownm or colnm.
direction	logic, whether this network is directed, the default is TRUE.
rmName	logic, whether to remove row names and column names in the adjacency matrix.
restValue	the value to fill in the blank edges.

Value

An adjacency matrix.

Examples

## Not run: 
edge = data.frame(c("a", "b", "c"), c("a", "c", "d"), c(1,1,1))
edge2Mat(edge, edge[,1], edge[,2])

nodes = unique(c(as.character(edge[,1]), as.character(edge[,2])))
edge2Mat(edge, nodes, nodes)

edge2Mat(edge, nodes, nodes,direction = FALSE)
edge2Mat(edge, nodes, nodes,direction = FALSE, rmName = TRUE)

edge = data.frame(c(1:3), c(3:5), c(1,1,1))
edge2Mat(edge,  edge[,1],  edge[,2] )

## End(Not run)
