Details

The argument format specifies the object that should be returned by the function. It can take the following values

"long"

produces a data set in which imputed data sets are stacked vertically. The following columns are added: 1) .imp referring to the imputation number, and 2) .id the row names of the original dataset

"stacked"

the same as "long", but without the inclusion of the two columns .imp and .id

"mids"

produces an object of class mids, which is the format used by the mice package.

Examples

if (FALSE) {
# Imputation with the MICT algorithm
imp <- seqimpute(data = gameadd, var = 1:4)

# The object imp is transformed to a dataframe, where completed datasets are
# stacked vertically

imp.stacked <- fromseqimp(
  data = imp,
  format = "stacked", include = FALSE
)
}
