In lavaan, is there a way to do factor analysis, specifying that the items are on different scales: both binary data and count data (with the count data itself on different metrics, since some items had a higher total possible count)?

I'll greatly appreciate any advice, thank you!

lavaan does not provide functionality for count variables.
