\title{
Load network from Cytoscape sif file
}
\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 \emph{read.graph} in the igraph package.
}
\usage{
loadNetwork.sif(sif.file, na.file, ea.file, format=c("graphNEL", "igraph"), directed=FALSE)
}
\arguments{
  \item{sif.file}{
Cytoscape sif file, containing the network.
}
  \item{na.file}{
File or vector of file with Cytoscape node attibutes. 
}
  \item{ea.file}{
File or vector of file with Cytoscape edge attibutes. 
}
  \item{format}{
Format of output graph, either \emph{graphNEL} or \emph{igraph}.
}
  \item{directed}{
Boolean value for directed or undirected graph.
}
}
\value{
Graph with loaded attributes.
