Create a permutation for an initial alignment. Either "random" or "reciprocal" may be specified as the mode argument.

1 | ```
InitialAlignment(psize, r=NA, mode="random")
``` |

`psize` |
size of the alignment |

`r` |
node similarity score matrix (required for mode 'reciprocal') |

`mode` |
type of initial alignment |

To create a random initial alignment of size psize, the InitialAlignment function can be used with the mode argument set to "random". If mode is set to "reciprocal", a reciprocal best match algorithm is applied to the input matrix R to find an initial alignment. This mode requires that the psize argument is sufficiently large to allow for the addition of dummy nodes to which unaligned nodes can formally be aligned.

The return value is a permutation vector of the specified size.
