further arguments for the write functions.
write.amelia writes the imputed datasets to a file or a set of files
using one of the following functions: write.csv,
write.dta, or write.table. You can pass arguments to
these functions from write.amelia.
When separate is TRUE, each imputed dataset is written
to its own file. If you were to set file.stem to
"outdata" and the extension to ".csv" , then the
resulting filename of the written files will be
outdata1.csv
outdata2.csv
outdata3.csv
...
and so on.
When separate is FALSE, the function adds a variable
called impvar to each dataset which indicates the imputed
dataset to which the row belongs. Then, each of the datasets are
stacked together to create one dataset. If orig.data is TRUE,
then the original, unimputed dataset is included at the top of the
stack, with its imputation number set to 0.
