Functions for loading and writing Pajek[http://vlado.fmf.uni-lj.si/pub/networks/pajek/] files

Description

Functions for reading/loading and writing Pajek files:

loadnetwork - Loads a Pajek ".net" file as a matrix. For now, only simple one-mode networks are supported.

savenetwork - Saves a matrix in to a Pajek ".net" file.

loadmatrix - Loads a Pajek ".mat" file as a matrix.

savematrix - Saves a matrix in to a Pajek ".mat" file.

loadvector - Loads a Pajek ".clu" file as a vector.

savevector - Saves a vector in to a Pajek ".clu" file.

Usage

loadnetwork(filename,useSparseMatrix=NULL,minN=50)
savenetwork(n, filename, twomode = 1, symetric = all(n==t(n)))
loadmatrix(filename)
savematrix(n, filename, twomode = 1)
loadvector(filename)
savevector(v, filename)

Arguments

filename The name of the file to be loaded or saved to.
useSparseMatrix Should a sparse matrix be use instead of the ordinary one? Sparse matices can only be used if package Matrix is installed. The default NULL uses sparsematrices for networks with more that minN vertices
minN The minimal number of units in the network to use sparse matrices.
n A matrix representing the network
twomode 1 for one-mode networks and 2 for two-mode networks
symetric If true, only the lower part of the matrix is used and the values are interpreted as "Edges", not "Arcs".
v A vector

Value

NULL, a matrix or a vector (see Description)
