Details
Multiply imputed data sets in SPSS are contained in a single file, in which an Imputation_ variable separates the original data and the various imputed data sets.
During export, factors are converted to numeric, whereas character variables are left "as is".
By default, write.mitmlSPSS generates a raw text file containing the data, along with a syntax file containing instructions for SPSS.
This syntax file mimics SPSS's functionality to read text files but circumvents certain problems that may occur when using the GUI.
In order to read in the data, the syntax file must be opened and executed using SPSS.
The syntax file may be altered manually if problems occur, for example, if the file path of the data file is not correctly represented in the syntax.
Alternatively, write.mitmlSAV may be used for exporting directly to the SPSS native .sav format.
However, this may offer less control over the data format.
Value
None (invisible NULL).
