Description Usage Arguments Details Value Author(s) Examples

Returns the difference of the input matrices. Output object is an
adjacency matrix where edges present in `matrix1`

but not `matrix2`

are returned. The edge value is maintained provided `cutoff`

= NULL.
Edges in both graphs failing to meet the `cutoff`

, if provided, are set
to zero before taking the graph difference.

1 |

`matrix1` |
Square matrix (e.g. correlation or adjacency) containing row/column labels |

`matrix2` |
Square matrix (e.g. correlation or adjacency) containing row/column labels |

`cutoff` |
The cutoff value. Edges less than this value (absolute value considered)are converted to zero. |

`...` |
Other parameters. |

Matrices must be square and have row and column labels. Output adjacency matrix can be used directly for creating a graph object.

`netDiff`

returns an adjacency matrix containing edges present in
`matrix1`

that are not present in `matrix2`

. Edges below
`cutoff`

are set to zero.
