Hi Stata Users

I have run multiple imputations using R's Amelia package and would
like to use the imputed dataset to analyse Mokken Scale Analysis.
But mokken requires the object to be a data frame. I tried
as.data.frame(x) and as.matrix(x) but it says that it cannot coerce
class amelia into a data frame or matrix.

australia93=as.data.frame(australia93)
Error in as.data.frame.default(australia93) :
 cannot coerce class '"amelia"' into a data.frame

coefH(australia93)
Error in check.data(X) : Data are not matrix or data.frame

Any help would be much appreciated.

Thanks,
Laura
