`loadmatrix`

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

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 adapted to be called within `loadpajek`

.

`loadnetwork3`

- Another version for reading networks.

`loadnetwork4`

- Another version for reading networks.

`loadpajek`

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

`loadvector`

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

`loadvector2`

- The same as above, but adapted to be called within `loadpajek`

- as a consequence not suited for reading clusters.

`savematrix`

- Saves a matrix into a Pajek ".mat" filename.

`savenetwork`

- Saves a matrix into a Pajek ".net" filename.

`savevector`

- Saves a vector into a Pajek ".clu" filename.

```
loadmatrix(filename)
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)
loadpajek(filename)
loadvector(filename)
loadvector2(filename)
savematrix(n, filename, twomode = 1)
savenetwork(n, filename, twomode = "default", symetric = NULL)
savevector(v, filename)
```

`filename` |
The name of the file to be loaded or saved to or an open file object. |

`useSparseMatrix` |
Should a sparse matrix be use instead of the ordinary one? Sparse matrices can only be used if package Matrix is installed. The default |

`minN` |
The minimal number of units in the network to use sparse matrices. |

`safe` |
If |

`closeFile` |
Should the connection be closed at the end. Should be always |

`fill` |
If |

`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 |

`v` |
A vector. |

NULL, a matrix or a vector.
