R Documentation

Calendar: year-month-day

Description

year_month_day() constructs the most common calendar type using the Gregorian year, month, day, and time of day components.

Usage

year_month_day(
  year,
  month = NULL,
  day = NULL,
  hour = NULL,
  minute = NULL,
  second = NULL,
  subsecond = NULL,
  ...,
  subsecond_precision = NULL
)

Arguments

`year`	`⁠[integer]⁠` The year. Values `⁠[-32767, 32767]⁠` are generally allowed.
`month`	`⁠[integer / NULL]⁠` The month. Values `⁠[1, 12]⁠` are allowed.
`day`	`⁠[integer / "last" / NULL]⁠` The day of the month. Values `⁠[1, 31]⁠` are allowed. If `"last"`, then the last day of the month is returned.
`hour`	`⁠[integer / NULL]⁠` The hour. Values `⁠[0, 23]⁠` are allowed.
`minute`	`⁠[integer / NULL]⁠` The minute. Values `⁠[0, 59]⁠` are allowed.
`second`	`⁠[integer / NULL]⁠` The second. Values `⁠[0, 59]⁠` are allowed.
`subsecond`	`⁠[integer / NULL]⁠` The subsecond. If specified, `subsecond_precision` must also be specified to determine how to interpret the `subsecond`. If using milliseconds, values `⁠[0, 999]⁠` are allowed. If using microseconds, values `⁠[0, 999999]⁠` are allowed. If using nanoseconds, values `⁠[0, 999999999]⁠` are allowed.
`...`	These dots are for future extensions and must be empty.
`subsecond_precision`	`⁠[character(1) / NULL]⁠` The precision to interpret `subsecond` as. One of: `"millisecond"`, `"microsecond"`, or `"nanosecond"`.

Details

Fields are recycled against each other.

Fields are collected in order until the first NULL field is located. No fields after the first NULL field are used.

Value

A year-month-day calendar vector.

Examples

# Just the year
x <- year_month_day(2019:2025)

# Year-month type
year_month_day(2020, 1:12)

# The most common use case involves year, month, and day fields
x <- year_month_day(2020, clock_months$january, 1:5)
x

# Precision can go all the way out to nanosecond
year_month_day(2019, 1, 2, 2, 40, 45, 200, subsecond_precision = "nanosecond")
