Re: [igraph] Delete all attributes

[Chris Watson]

Thanks. My use case would be after using "rewire" to create a random graph. I work w/ pretty small graphs so it only takes a couple milliseconds to delete them all.

Hi Chris,

Yes, that's the way to do it - we have no dedicated function for this.
However, you can also create a new graph from the edge list of the old
graph, which is effectively the same thing (I guess), and it is
probably faster.
