\usage{
year_day(
year,
day = NULL,
hour = NULL,
minute = NULL,
second = NULL,
subsecond = NULL,
...,
subsecond_precision = NULL
)
}
\arguments{
\item{year}{\verb{[integer]}
The year. Values \verb{[-32767, 32767]} are generally allowed.}
\item{day}{\verb{[integer / NULL]}
The day of the year. Values \verb{[1, 366]} are allowed.}
\item{hour}{\verb{[integer / NULL]}
The hour. Values \verb{[0, 23]} are allowed.}
\item{minute}{\verb{[integer / NULL]}
The minute. Values \verb{[0, 59]} are allowed.}
\item{second}{\verb{[integer / NULL]}
The second. Values \verb{[0, 59]} are allowed.}
\item{subsecond}{\verb{[integer / NULL]}
The subsecond. If specified, \code{subsecond_precision} must also be specified
to determine how to interpret the \code{subsecond}.
If using milliseconds, values \verb{[0, 999]} are allowed.
If using microseconds, values \verb{[0, 999999]} are allowed.
If using nanoseconds, values \verb{[0, 999999999]} are allowed.}
\item{...}{These dots are for future extensions and must be empty.}
\item{subsecond_precision}{\verb{[character(1) / NULL]}
The precision to interpret \code{subsecond} as. One of: \code{"millisecond"},
\code{"microsecond"}, or \code{"nanosecond"}.}
}
\value{
A year-day calendar vector.
}
\description{
\code{year_day()} constructs a calendar vector from the Gregorian
year and day of the year.
}
\details{
Fields are recycled against each other using
\link[vctrs:theory-faq-recycling]{tidyverse recycling rules}.
Fields are collected in order until the first \code{NULL} field is located. No
fields after the first \code{NULL} field are used.
}
\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")
