textAlong about ggraph HOT 8 CLOSED

That is strange as it should be available (it is imported from grid in the namespace file)

Can I get you to try and install the latest GitHub version, and if the problem persists, try to load grid
explicitly (library(grid)) and see if that helps. If there's still a problem I would like to get a minimal reproducible example along with your session info...

from ggraph.

Hmm... It still shouldn't do that - can you share the error producing code along with your session info

Hmm... I cannot reproduce. Can I get you to test if you get the error when you run the code without ggiraph calls?

from ggraph.

It works fine without ggiraph calls.

from ggraph.

There's some strangeness going on in that interaction then. As it is solved by loading grid I won't look more into it now as ggraph itself works, but might look further when time permits

from ggraph.

Ok, thank you!
