Functions for reading/loading and writing Pajek files:

loadnetwork - Loads a Pajek ".net" filename as a matrix. For now, only simple one and two-mode networks are supported (eg. only single relations, no time information).

loadnetwork2 - The same as above, but adopted to be called withih loadpajek

loadnetwork3 - Another version for reading networks.

loadnetwork4 - Another version for reading networks.

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

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

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

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

loadvector2 - The same as above, but adopted to be called withih loadpajek - as a consequence not suited for reading clusters

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

loadpajek - Loads a Pajek project filename (".paj") as a list with the following components: Networks, Partitions, Vectors and Clusters. Clusters and hierarchies are dissmised.

loadnetwork(filename, useSparseMatrix = NULL, minN = 50)
loadnetwork2(filename, useSparseMatrix = NULL, minN = 50, safe =
                 TRUE, closeFile = TRUE)
loadnetwork3(filename, useSparseMatrix = NULL, minN = 50)
loadnetwork4(filename, useSparseMatrix = NULL, minN = 50, fill = FALSE)
savenetwork(n, filename, twomode = "default", symetric = NULL)
loadmatrix(filename)
savematrix(n, filename, twomode = 1)
loadvector(filename)
loadvector2(filename)
savevector(v, filename)
loadpajek(filename)

`filename`	The name of the filename to be loaded or saved to or an open file object.
`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. Default sets the argument to 1 for square matrices and to 2 for others.
`symetric`	If true, only the lower part of the matrix is used and the values are interpreted as "Edges", not "Arcs".
`v`	A vector.
`fill`	If TRUE then in case the rows have unequal length, blank fields are added.
`safe`	If `FALSE` error will occur if not all vertices have labels. If `TRUE` reading works faster.
`closeFile`	Should the connection be closed at the end. Should be always `TRUE` if function is used directly.
