mitml (version 0.3-4)

write.mitmlSAV: Write mitml objects to native SPSS format

Description

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.

Usage

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, to be specified with or without file extension. The file extension (.sav) is appended if necessary.

Value

None (invisible NULL).

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. Thus, write.mitmlSAV exports directly to the native SPSS format.

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