Appends the czech_date class attribute to the input object. Date of class
czech_date is printed as a date in long format with correct Czech
grammatical case (see Details and Grammatical cases section below).
Usage
as_czech_date(date, case = "genitive")
Arguments
- date
date or date-like object to parse.
- case
character, either "nominative", "locative" or "genitive"
(default) or any unambiguous abbreviation of these.
Value
Same as input, but with class czech_date and attribute
gramm_case.
Details
The grammatical case should be specified as and argument to print()
method, but for convenience, you can predefine it in as_czech_date call
directly. It is then stored as an attribute, later grabbed by the print
method.
Note that as opposed to other date formating functions in R,
as_date_czech trims leading zeros.
Grammatical cases
Three grammatical cases are supported:
nominative – native form, i.e. "leden" in Czech
locative – "in ...", i.e. "v lednu" in Czech
genitive – "the 'nth' of ...", i.e. "5. ledna" in Czech
Czech months listed by case are available in .czech_months.
Examples
Sys.time() %>% as_czech_date()
#> [1] "10. října 2024"
# in "nominative" grammatical case (note the abbreviation)
Sys.time() %>% as_czech_date("nom")
#> [1] "10. říjen 2024"
