Error missing value where TRUE/FALSE needed

[l-psych]

Hi!
Thanks for this great package. I have been using it for a while now and have never run into problems. However, I am getting an error message when I want to calculate the omega and related interval for the internal consistency of a scale. I get the following error message:

scaleStructure(dat=CALISCrel_6mfu)
Error in if (se != "none" && any(errorcheck <= 0)) converged <- FALSE :
missing value where TRUE/FALSE needed
In addition: Warning messages:
1: In lav_model_estimate(lavmodel = lavmodel, lavpartable = lavpartable, :
lavaan WARNING: the optimizer warns that a solution has NOT been found!
2: In lav_model_estimate(lavmodel = lavmodel, lavpartable = lavpartable, :
lavaan WARNING: the optimizer warns that a solution has NOT been found!
3: In lav_model_estimate(lavmodel = lavmodel, lavpartable = lavpartable, :
lavaan WARNING: the optimizer warns that a solution has NOT been found!
4: In lav_model_estimate(lavmodel = lavmodel, lavpartable = lavpartable, :
lavaan WARNING: the optimizer warns that a solution has NOT been found!

The data looks like this:

head(CALISCrel_6mfu)
dccalis1 dccalis2a dccalis2b dccalis2c dccalis2d dccalis2e dccalis2f dccalis2g dccalis2h dccalis3

That is very odd. It appears to be an error from a lavaan function.

The error suggests that either "se" is missing (NA), or "errorcheck" is.

Is the data open, and if so, could you link to it perhaps? Then I can see whether I can reproduce the error.

Hello, I have the very same problem, and it happens with two almost identical data sets, as if randomly…. it happens with every scale analysis related function, scaleStructure, scaleReliability, scaleDiagnosis(). I also changed the colnames to not including any whitespace, dots or other weird characters. There are still some important variables that I simply cannot apply the usf related functions on, I would be very glad if this could be fixed, or at least, a workaround being shown, (for „beginneRs“).
