Write mitml objects to native SPSS format

Saves objects of class mitml in the .sav format used by the statistical software SPSS (IBM Corp., 2013). The function serves as a front-end for write_sav from the haven package.

write.mitmlSAV(x, filename)

Arguments

x: An object of class mitml or mitml.list as produced by panImpute, jomoImpute, mitmlComplete, or similar).
filename: Name of the destination file. The file extension (.sav) is appended if needed.

Details

This function exports multiply imputed data sets to a single .sav file, in which an Imputation_ variable separates the original data and the various imputed data sets. This allows exporting imputed data directly to the native SPSS format.

Alternatively, write.mitmlSPSS may be used for creating separate text and SPSS syntax files, which offers more control over the data format.

Value

None (invisible NULL).
