levels

What should be used for the factor levels: the labels, the values or labels prefixed with values?

nolabel_to_na

If some values doesn't have a label, automatic labels will be created, except if nolabel_to_na is TRUE.

Examples

to_character(v, nolabel_to_na = TRUE)
to_character(v, "v")
to_character(v, "p")
