Retrieve all concept code options of all Nomis datasets, concept code options for a given dataset, or the all the options for a given concept variable from a particular dataset. Specifying concept will return all the options for a given variable in a particular dataset.

If looking for a more detailed overview of all available metadata for a given dataset, see nomis_overview().

nomis_get_metadata(
  id,
  concept = NULL,
  type = NULL,
  search = NULL,
  additional_queries = NULL,
  ...,
  tidy = FALSE
)

Arguments

id

The ID of the particular dataset. Returns no data if not specified.

concept

A string with the variable concept to return options for. If left empty, returns all the variables for the dataset specified by id. Codes are not case sensitive. Defaults to NULL.

type

A string with options for a particular code value, to return types of variables available for a given code. Defaults to NULL. If concept == NULL, type will be ignored.

search

A string or character vector of strings to search for in the metadata. Defaults to NULL. As in nomis_search(), the wildcard character * can be added to the beginning and/or end of each search string.

additional_queries

Any other additional queries to pass to the API. See https://www.nomisweb.co.uk/api/v01/help for instructions on query structure. Defaults to NULL. Deprecated in package versions greater than 0.2.0 and will eventually be removed.

...

Use to pass any other parameters to the API.

tidy

If TRUE, converts tibble names to snakecase.

Value

A tibble with metadata options for queries using nomis_get_data().
