Hi,
Some scripts which I'm sure have run without problems a couple of months ago are now giving me the following error:
> equateAEModelFit <- mxRun(equateAEModel)
Running equateAE
Error in slot(model, name) :
no slot of name ".newobjects" for this object of class "MxModel"
Any ideas what's happening?
Thanks,
Paul
This solution should work: http://openmx.psyc.virginia.edu/thread/774
Thanks Michael,
But I don't follow this - sorry.
When I try to substitute using:
newModel <- mxModel()
oldSlotNames <- slotNames(equateAEModel)
for(i in 1:length(oldSlotNames)) {
slot(newModel, oldSlotNames[[i]]) <- slot(equateAEModel, oldSlotNames[[i]])
}
I get a similar error:
Error in slot(equateAEModel, oldSlotNames[[i]]) :
no slot of name ".newobjects" for this object of class "MxModel"
Can you explain what I need to?
Can you run the following and tell me what is stored in the variable 'slots'?
slotN <- slotNames(equateAEModel)
If you see ".newobjects", ".newobjective", and ".newtree" in the output above, then try:
slotN <- setdiff(slotN, c('.newobjects', '.newobjective', '.newtree'))
And then try:
newModel <- mxModel()
for(i in 1:length(slotN)) {
slot(newModel, slotN[[i]]) <- slot(equateAEModel, slotN[[i]])
}
That seems to work. Thanks a lot.
