write.datlist: Write a List of Multiply Imputed Datasets

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

Write a List of Multiply Imputed Datasets

Description

Writes a list of multiply imputed datasets.

Usage

write.datlist(datlist, name, include.varnames=TRUE, type="csv2",
     separate=TRUE, Mplus=FALSE, round=NULL, Rdata=TRUE,
     subdir=TRUE, ...)

Arguments

datlist	List of imputed datasets. Can also be an object of class mids, mids.1chain or imputationList
name	Name of files to be saved
include.varnames	Logical indicating whether variables should be saved
type	File type of datasets to be saved, see save.data.
separate	Logical indicating whether imputed datasets should be written in separate files.
Mplus	Logical indicating whether files should be written for usage in Mplus software
round	Number of digits to round after decimal. The default is no rounding.
Rdata	Logical indicating whether datlist should also be saved in R binary format.
subdir	Logical indicating whether results should be written into a subdirectory.
...	Further arguments to be passed to save.data.
