The double bracket operator can be used on vertex sequences, to print the meta-data (vertex attributes) of the vertices in the sequence.

## S3 method for class 'igraph.vs' x[[...]]

`x` |
A vertex sequence. |

`...` |
Additional arguments, passed to |

Technically, when used with vertex sequences, the double bracket operator does exactly the same as the single bracket operator, but the resulting vertex sequence is printed differently: all attributes of the vertices in the sequence are printed as well.

See `[.igraph.vs`

for more about indexing vertex sequences.

The double bracket operator returns another vertex sequence, with meta-data (attribute) printing turned on. See details below.
