Error in lav2standata(lavobject) : object 'ptot' not found

[ecmerkle]

Thanks for the report! The ptot object is internal to blavaan and is used to translate the model to Stan. So something is wrong, but I haven't been able to reproduce the error for this type of model. It might help to know what version of blavaan and lavaan you are using (say, using sessionInfo()), and it would help to see the dataset if you can share it.

I looked at this some more, and I am guessing you have missing data (NA values). If so, blavaan cannot yet handle missing data in two-level models. But I should improve the error handling here.

Hi, thanks for getting back. Yes, I did have missing data. Let me try without and see if it works.

No problem, and if you can install from github, it should now automatically do listwise deletion and display a NOTE about it.

Instructions for installing from github are at the bottom of the repo's page.

The fix described above is now available in blavaan 0.5-4 on CRAN. If you have further problems here, please reopen!
