Summary of lavaan.mi fails with unclear error #75

Closed LukasWallrich closed 4 years ago

LukasWallrich commented 4 years ago

Hi there,

I am running a mediation model with multiple imputation and am getting the following error in the summary function: 

Error in if (attr(x, "se") == "robust.huber.white" && attr(x, "information.meat") !=  : 
  missing value where TRUE/FALSE needed
In addition: Warning message:
In if (attr(x, "information") == "observed") { :
  the condition has length > 1 and only the first element will be used

The model is fitted with mod <- semTools::runMI(model, imp_long_list_with_dummy_sd, fun = "sem", sampling.weights = "wt"). coef() works fine. Any suggestions how I can proceed, particularly in order to get significance tests for the coefficients, would be very much appreciated.

I am happy to provide more information, but am not sure what would be most helpful.

traceback() shows that the error appears to come from print.lavaan.parameterEstimates, probably because the "information.meat" attribute is not set - but as I don't know how to trace/debug methods, I can't investigate further.

(h1.)information.meat are new attributes of the lavaan.parameterEstimates class. I have just added them to the summary() method for lavaan.mi objects, so this should be resolved in the development version (0.5-3.909; see the Wiki for syntax to install from GitHub). If the error goes away, please close the issue; otherwise, I might need a reproducible example to find out what is going on. Thanks.
