Description

Igraph's internal data representation changes sometimes between versions. This means that it is not possible to use igraph objects that were created (and possibly saved to a file) with an older igraph version.

Usage

Arguments

Details

graph_version queries the current data format, or the data format of a possibly older igraph graph.
