Function to extract the possible values from a variable. Values for continuous variables are not extractable, which is why the function returns a warning message in this case.
Arguments
- code
Character string with a maximum length of 15 characters. Code from a GENESIS, Zensus 2022 or regionalstatistik.de object. Only one code per iteration.
- database
Character string. Indicator if the GENESIS ('genesis'), Zensus 2022 ('zensus') or regionalstatistik.de ('regio') database is called. Default option is 'all'.
- area
Character string. Indicator from which area of the database the results are called. In general, 'all' is the appropriate solution. Default option is 'all'. Not used for 'statistics'.
- sortcriterion
Character string. Indicator if the output should be sorted by 'code' or 'content'. This is a parameter of the API call itself. The default is 'code'.
- error.ignore
Boolean. Indicator for values if the function should stop if an error occurs or no object for the request is found or if it should produce a token as response. Default option is 'TRUE', this prevents the function to stop even if a variable has no further explanation (often the case for numerical variables).
- verbose
Boolean. Indicator if the output of the function should include detailed messages and warnings. Default option is 'TRUE'. Set the parameter to 'FALSE' to suppress additional messages and warnings.
