Igraph data structure versions
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
graph_version(graph)Arguments
- graph
The input graph. If it is missing, then the version number of the current data format is returned.
Details
graph_version queries the current data format,
or the data format of a possibly older igraph graph.
upgrade_graph can convert an older data format
to the current one.
Value
A character scalar.
See Also
