complete.miceadds: Creates Imputed Dataset from a mids.nmi or mids.1chain Object

Description

Creates imputed dataset from a mids.nmi or mids.1chain object.

Usage

complete.mids.nmi( x, action=c(1,1) )
complete.mids.1chain( x, action=1 )

Arguments

x

Object of class mids.nmi (for complete.mids.nmi) or mids.1chain (for complete.mids.1chain)

action

A vector of length two indicating to indices of between and within imputed dataset for for complete.mids.nmi and an integer for the index of imputed dataset for complete.mids.1chain.
