I am lost and I kindly ask you, dear R community, for your help:

```
> raschmix(TPsubmatrix, k=2, scores = "saturated")
2 : *Error in matrix(1, nrow = sum(groups$groupfirst)) : data is too long
In addition: Warning message:
In min(which(rs > 0)) : no non-missing arguments to min; returning Inf
*Error in matrix(1, nrow = sum(groups$groupfirst)) : data is too long
*Error in matrix(1, nrow = sum(groups$groupfirst)) : data is too long
Error in stepFlexmix(.response ~ 1, data = d, k = k, nrep = nrep, cluster = cluster, :
no convergence to a suitable mixture
```

Does anyone has experience with raschmix() and knows how I have to save my data, so that it can be analysed?

This would be so amazing!

Thank you very much for your help, interest and effort in any case!
