Description Usage Arguments Value See Also Examples

If attributes are supplied, and they are not present in the graph,
their values for the original vertices of the graph are set to
`NA`

.

1 | ```
add_vertices(graph, nv, ..., attr = list())
``` |

`graph` |
The input graph. |

`nv` |
The number of vertices to add. |

`...` |
Additional arguments, they must be named, and they will be added as vertex attributes, for the newly added vertices. See also details below. |

`attr` |
A named list, its elements will be added as vertex attributes, for the newly added vertices. See also details below. |

The graph, with the vertices (and attributes) added.
