to_codes(x, codelist, locale = cl_locale(codelist))

Arguments

x	character vector with labels.
...	used to pass arguments to other methods.
codelist	a codelist object or a data.frame that is a valid code list or and object that has a 'codelist' attribute containing a codelist.
locale	use the codes from the given locale. Should be a character vector of length 1.

to_codes has the same functionality as a call to codes.default.
