##### 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.
