### Description

Returns a logical value for each specified vertex, indicating if it has any incident (in or out) edges. Checks all vertices by default

### Usage

``` |

### Arguments

`net` |
a |

`v` |
integer vector of vertex ids to check |

### Value

returns a logical vector with the same length as v, with TRUE if the vertex is involved in any edges, FALSE if it is an isolate.
