no slot of name "runstate" for this object of class "MxModel" error in Jupyter lab

[arinbasu]

Hi Tim, I ran the following umxACE model in a Jupyter lab

data(twinData)
selDVs = c("bmi")
dz = twinData[twinData$zygosity == "DZFF",]
mz = twinData[twinData$zygosity == "MZFF",]
m1 = umxACE(
    selDVs = selDVs,
    dzData = dz,
    mzData = mz,
    sep = ""
    )
summary(m1)

This produced the following error: Error in slot(value, what): no slot of name "runstate" for this object of class "MxModel"

It's because the model has not yet been run. This garbled error message is being rewritten. So it should work if you do summary(mxRun(m1)) instead.

You may need to update umx. The 'runstate' slot was eliminated from the MxModel class definition in OpenMx v2.20.

It's because the model has not yet been run.

That's not why. umx's on-load default behavior is to automatically run a umx model after it's created.

I stand corrected. Those automagic things have a way of catching people out.

Thanks Rob and Mike. I uninstalled umx and reinstalled it with devtools::install_github("tbates/umx") With the current version of OpenMx (2.20.6.6), the problem is now resolved. Thank you again for your fast solution. I will close this issue now.

Glad to help.
