umxVersion() vs. umxVersion(“umx”).

"How much of a problem is this error when we run umXVersion(“umx”)?:
"Error in mxOption(model, "Default optimizer") : trying to get slot "options" from an object of a basic class ("character") with no slot?”


You should just run
umxVersion()

It is thinking that the first item you provide is a model, and tries to see what version you ran under.
