# igraph-vs-indexing2

##### Select vertices and show their metadata

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

##### Usage

```
# S3 method for igraph.vs
[[(x, ...)
```

##### Arguments

- x
A vertex sequence.

- ...
Additional arguments, passed to

`[`

.

##### Details

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.

##### Value

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