`get.neighborhood`

returns the IDs of all vertices belonging to the in, out, or combined neighborhoods of `v`

within network `x`

.

1 2 | ```
get.neighborhood(x, v, type = c("out", "in", "combined"),
na.omit=TRUE)
``` |

`x` |
an object of class |

`v` |
a vertex ID |

`type` |
the neighborhood to be computed |

`na.omit` |
logical; should missing edges be ignored when obtaining vertex neighborhoods? |

Note that the combined neighborhood is the union of the in and out neighborhoods – as such, no vertex will appear twice.

A vector containing the vertex IDs for the chosen neighborhood.
