write.mice.imputation: Export Multiply Imputed Datasets from a 'mids' Object

In miceadds: Some Additional Multiple Imputation Functions, Especially for 'mice'

Export Multiply Imputed Datasets from a mids Object

Description

Exports multiply imputed datasets and information about the imputation. Objects of class mids (generated by mice::mice) and mids.1chain (generated by mice.1chain) are supported.

Usage

write.mice.imputation(mi.res, name, include.varnames=TRUE,
      long=TRUE, mids2spss=TRUE, spss.dec=",", dattype=NULL)

Arguments

mi.res	Object of class mids or mids.1chain
name	Name of created subdirectory and datasets
include.varnames	An optional logical indicating whether variable names should be included in the imputed dataset. The default is TRUE.
long	An optional logical indicating whether the dataset should also be saved in a long format?
mids2spss	An optional logical indicating whether a syntax for reading imputed datasets in SPSS should be included
spss.dec	SPSS decimal separator (can be "," or ".")
dattype	Format of the saved dataset: csv or csv2

Value

Several files are saved using impxxx (the name) as the prefix:

impxxx.Rdata	Saved object of class mids
impxxx__DATALIST.Rdata	Saved object of a list containing multiply imputed datasets
impxxx__IMP_LIST	File with list of multiply imputed datasets
impxxx__IMP_SUMMARY	Summary file of the imputation
impxxx__IMPDATA_nn	Imputed datasets nn
impxxx__IMPMETHOD	File containing imputation methods
impxxx__LEGENDE	File with variable names of the dataset
impxxx__LONG	Imputed datasets in long format
impxxx__PREDICTORMATRIX	File containing the predictor matrix
impxxx__SPSS.sps	SPSS syntax for reading the corresponding txt file into SPSS format.
