R igraph manual pages

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 [.

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.

Value

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