Build an ISO8601 date pattern from the year, middle (month or week), day, and time patterns.

pattern_ISO8601_date_builder.Rd

Build an ISO8601 date pattern from the year, middle (month or week), day, and time patterns.

Usage

pattern_ISO8601_date_builder(
  truncated,
  pattern_year,
  pattern_middle,
  pattern_day,
  pattern_time,
  allow_before_year_1583
)

Arguments

truncated

Should the date/time be allowed to be truncated? An integer indicating the highest required precision (0=second is required, 1=minute, 2=hour, 3=day, 4=month or week, 5=year, 6=none). A value of 6 will allow an empty string to match.

pattern_year

The pattern for the ISO8601 year (ignored if allow_before_year_1583 is given); if null, only the middle and day part will be returned without a year part.

pattern_middle

The pattern for the ISO8601 month or week (or NULL for ordinal dates)

pattern_day

The pattern for the ISO8601 day

pattern_time

A string to add to the day for including time with date (see pattern_ISO8601_time())

allow_before_year_1583

Should years between 0 and 1582 be allowed (they are only allowed in ISO 8601 with mutual agreement)
