Description
as.ISO8601
methods would be useful for all the date, date/time, period, duration, and interval functions.
To make this as useful as possible, I think it would benefit to not use as.character
and make a new as.ISO8601
generic function with arguments:
x
: The object to convertformat
: This would depend on what is being represented:- With dates, it could be "ymd" (year month day), "ywd" (year week day), "yd" (year day in YYYY-DDD format), "y" (year only), "m" (month only), "md" (month day only)
- With times, it could be "hms", "hm", or "h"
- With date/times, it could be any pair of the options for dates and times separated by a "T" (default "ymdThms"). I chose "T" rather than something else to align with the expected output as defined in the ISO standard.
- Periods would share the format specifier with date, times, or date/times.
include_tz
: ifNULL
(default), include/exclude the time zone from the date/time based on the input data. IfFALSE
, exclude the time zone from the representation, and ifTRUE
include the time zone in the representation. (It would be ignored if time zone does not apply to the output format.)repeat
: (default:NULL
) For intervals, repeating could be specified by setting to a non-NULL, positive integer orInf
for indefinite, future repeats.repeat_start
: (default:NULL
) For intervals, repeat start date/time. (Must be a date, time, or date/time object type.)
(As initially discussed in #362)
