\item{levels}{How to create the levels of the generated factor:
|
|
|
|
* "default": uses labels where available, otherwise the values.
|
|
Labels are sorted by value.
|
|
* "both": like "default", but pastes together the level and value
|
|
* "label": use only the labels; unlabelled values become `NA`
|
|
* "values": use only the values}
|
|
|
|
\item{ordered}{If `TRUE` create an ordered (ordinal) factor, if
|
|
`FALSE` (the default) create a regular (nominal) factor.}

|
}

|
\description{
|
|
This extends [forcats::as_factor()] as well as [haven::as_factor()], by appending
|
|
original attributes except for "class" after converting to factor to avoid
|
|
ta loss in case of rich formatted and labelled data.
