This is a helper function for RelationStrengthSimilarity that returns the component of RSS contributed by paths of one particular length r.

1 | ```
RssThisRadius(x, v1, v2, r, prepped = FALSE)
``` |

`x` |
numeric matrix, adjacency matrix where the [i,j] entry gives the strength of the link from node i to node j. |

`v1` |
numeric, index of the 'from' node. |

`v2` |
numeric, index of the 'to' node. |

`r` |
numeric, length of paths examined from |

`prepped` |
logical, whether or not the adjacency
matrix |

numeric, the part of the Relation Strength Similarity
score from `v1`

to `v2`

contributed by paths of
length `r`

.
