loadNetwork.sif: Load network from Cytoscape sif file

In BioNet: Routines for the functional analysis of biological networks

Description

The function loads a network from a Cytoscape sif file. Edge attributes are provided in the ea.file or vector of ea.files. The node attributes are provided the same way. For other formats see read.graph in the igraph package.

Usage

loadNetwork.sif(sif.file, na.file, ea.file, format=c("graphNEL", "igraph"), directed=FALSE)

Arguments

sif.file	Cytoscape sif file, containing the network.
na.file	File or vector of file with Cytoscape node attibutes.
ea.file	File or vector of file with Cytoscape edge attibutes.
format	Format of output graph, either graphNEL or igraph.
directed	Boolean value for directed or undirected graph.

Value

Graph with loaded attributes.

Examples

## Not run: lib <- file.path(.path.package("BioNet"), "extdata") 
# load interaction file, node attribute file with a node weight of 2 for each node and the edge attribute file with a edge weight of 1 for each edge
network <- loadNetwork.sif(sif.file=file.path(lib,"cytoscape.sif"), na.file=file.path(lib,"n.weight.NA"), ea.file=file.path(lib,"weight.EA"), format="graphNEL", directed=FALSE);
network;
nodeData(network);
edgeData(network);

## End(Not run)
