Error in graph_to_tree(graph, mode = direction) : Graph must be directed #28

When I tried to visualize the network, I keep getting this error: Error in graph_to_tree(graph, mode = direction) : Graph must be directed. Any suggestion on what might be the problem?

Hi- hard to help without knowing which functions you are using and what your data look like. If you post your code here either I or someone else may be able to help (but I am a bit short on time right now unfortunately, so apologies in advance if I can't get back to you right away)

I faced the same issue - I circumvented it by setting ggraph(pruned) to ggraph(pruned, 'tree') in the function VisTextNet() as the suggested here.

Probably, the ggraph package changed - so this may be something to change in case you consider maintaining the package.
