Re: [amelia] writing imputed datasets to files

Hi - I ran across this problem when helping someone attempting to do imputation on a large dataset. To conserve memory, she would like to write each imputed dataset to a file and then discard it before moving on to the next imputation. I think that should be possible using the keep.data=F and write.out = T arguments. Setting these options appears to erase the imputed datasets before they are sent to a file, and return NAs instead: if (keep.data) { impdata[[i]] <- impfill(x.orig = data, x.imp = ximp, noms = prepped$noms, ords = prepped$ords) names(impdata)[i] <- paste("m", i, sep = "") } else { impdata[[i]] <- NA } if (write.out) { write.csv(impdata[[i]], file = paste(prepped$outname, i, ".csv", sep = "")) } Cheers, Mike --- Michael Kellermann Ph.D Candidate, Department of Government Harvard University kellerm(a)fas.harvard.edu http://people.fas.harvard.edu/~kellerm/ - Amelia mailing list served by Harvard-MIT Data Center [Un]Subscribe/View Archive: http://lists.gking.harvard.edu/?info=amelia
