Hi Team,

I tried using fa.ply function for a dataset with ordinal and nominal variables.Its giving the following Warning.Is it a bug?Or we need to use some other procedure for factor analysis of ordinal/nominal data?

Code:-
faPCdirect <- fa.poly(mydata, nfactors=12, rotate="varimax")

Warning:-
The items do not have an equal number of response alternatives, global set to FALSE

The items do not have an equal number of response alternatives, global set to FALSE
The estimated weights for the factor scores are probably incorrect.  Try a different factor extraction method.
There were 35 warnings (use warnings() to see them)

Regards
Sarbani
