This is a year-quarter-day method for the calendar_start() and calendar_end() generics. They adjust components of a calendar to the start or end of a specified precision.

# S3 method for clock_year_quarter_day
calendar_start(x, precision)

# S3 method for clock_year_quarter_day
calendar_end(x, precision)

Arguments

x

[clock_year_quarter_day]

A year-quarter-day vector.

precision

[character(1)]

One of:

  • "year"

  • "quarter"

  • "day"

  • "hour"

  • "minute"

  • "second"

  • "millisecond"

  • "microsecond"

  • "nanosecond"

Value

x at the same precision, but with some components altered to be at the boundary value.

Examples

x <- year_quarter_day(2019:2020, 2:3, 5, 6, 7, 8, start = clock_months$march) x
#> <year_quarter_day<March><second>[2]> #> [1] "2019-Q2-05 06:07:08" "2020-Q3-05 06:07:08"
# Compute the last moment of the fiscal quarter calendar_end(x, "quarter")
#> <year_quarter_day<March><second>[2]> #> [1] "2019-Q2-92 23:59:59" "2020-Q3-91 23:59:59"
# Compare that to just setting the day to `"last"`, # which doesn't affect the other components set_day(x, "last")
#> <year_quarter_day<March><second>[2]> #> [1] "2019-Q2-92 06:07:08" "2020-Q3-91 06:07:08"
# Compute the start of the fiscal year calendar_start(x, "year")
#> <year_quarter_day<March><second>[2]> #> [1] "2019-Q1-01 00:00:00" "2020-Q1-01 00:00:00"
as_date(calendar_start(x, "year"))
#> [1] "2018-03-01" "2019-03-01"
