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
