I'm encountering an annoying bug with the summary.MxModel method.
When I open a saved R workspace that have MxModels saved it and load the OpenMx library, the summary() command doesn't work properly. Instead of running the summary.MxModel method, it just runs the generic summary method, giving something like:
Length Class Mode
1 MxRAMModel S4
If I first open R, load OpenMx, then load the saved workspace into the environment, summary() works as expected.
Several other people in my lab have also encountered the same issue. I've not had the same problem with other S4 packages (e.g., lme4). Is there something I could do or that can be fixed in the OpenMx code so that the summary call works with saved workspaces? It would make my workflow a lot easier. (It's also been a frequent source of confusion for new users I've worked with.)
Thanks!
