as_year_quarter_day() converts a vector to the year-quarter-day calendar. Time points, Dates, POSIXct, and other calendars can all be converted to year-quarter-day.

as_year_quarter_day(x, ..., start = NULL)

Arguments

x

[vector]

A vector to convert to year-quarter-day.

...

These dots are for future extensions and must be empty.

start

[integer(1) / NULL]

The month to start the fiscal year in. 1 = January and 12 = December.

If NULL:

  • If x is a year-quarter-day, it will be returned as is.

Value

A year-quarter-day vector.

Examples

# From Date as_year_quarter_day(as.Date("2019-01-01"))
#> <year_quarter_day<January><day>[1]> #> [1] "2019-Q1-01"
as_year_quarter_day(as.Date("2019-01-01"), start = 3)
#> <year_quarter_day<March><day>[1]> #> [1] "2019-Q4-32"
# From POSIXct, which assumes that the naive time is what should be converted as_year_quarter_day(as.POSIXct("2019-01-01 02:30:30", "America/New_York"))
#> <year_quarter_day<January><second>[1]> #> [1] "2019-Q1-01 02:30:30"
# From other calendars tuesday <- 3 as_year_quarter_day(year_month_weekday(2019, 2, tuesday, 2))
#> <year_quarter_day<January><day>[1]> #> [1] "2019-Q1-43"
# Converting between `start`s x <- year_quarter_day(2019, 01, 01, start = 2) x
#> <year_quarter_day<February><day>[1]> #> [1] "2019-Q1-01"
# Default keeps the same start as_year_quarter_day(x)
#> <year_quarter_day<February><day>[1]> #> [1] "2019-Q1-01"
# But you can change it as_year_quarter_day(x, start = 1)
#> <year_quarter_day<January><day>[1]> #> [1] "2018-Q1-32"
