This is an iso-year-week-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_iso_year_week_day
calendar_start(x, precision)

# S3 method for clock_iso_year_week_day
calendar_end(x, precision)

Arguments

x

[clock_iso_year_week_day]

A iso-year-week-day vector.

precision

[character(1)]

One of:

  • "year"

  • "week"

  • "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 <- iso_year_week_day(2019:2020, 5, 6, 10) x
#> <iso_year_week_day<hour>[2]> #> [1] "2019-W05-6 10" "2020-W05-6 10"
# Compute the last moment of the last iso week of the year calendar_end(x, "year")
#> <iso_year_week_day<hour>[2]> #> [1] "2019-W52-7 23" "2020-W53-7 23"
# Compare that to just setting the week to `"last"`, # which doesn't affect the other components set_week(x, "last")
#> <iso_year_week_day<hour>[2]> #> [1] "2019-W52-6 10" "2020-W53-6 10"
