igraph (version 1.0.0)

igraph-es-indexing2: Select edges and show their metadata

Description

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

Usage

## S3 method for class 'igraph.es':
[[(x, ...)

Arguments

x

An edge sequence.

...

Additional arguments, passed to [.

Value

• Another edge sequence, with metadata printing turned on. See details below.

Details

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

See [.igraph.es for more about indexing edge sequences.
