A `coding` object holds a list of `code`s that map vector values to human readable labels. An abstraction of factors, this data structure is designed to be portable and not directly attached to the underlying data. Moreover, `coding` objects can be "linked" for recoding and data lineage purposes. An "empty coding" is used to represent data that has no categorical interpretation.
coding(..., .label = NULL)
empty_coding()A collection of `code` objects
A label for this coding, available for interoperability
A `coding` object that contains each `code` input
