R Documentation

Calendar: year-day

Description

year_day() constructs a calendar vector from the Gregorian year and day of the year.

Usage

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

Arguments

`year`	`⁠[integer]⁠` The year. Values `⁠[-32767, 32767]⁠` are generally allowed.
`day`	`⁠[integer / NULL]⁠` The day of the year. Values `⁠[1, 366]⁠` are allowed.
`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-day calendar vector.

Examples

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

year_day(2020, 1:10)

# Last day of the year, accounting for leap years
year_day(2019:2021, "last")

# Precision can go all the way out to nanosecond
year_day(2019, 100, 2, 40, 45, 200, subsecond_precision = "nanosecond")
