year-month-day-boundary {clock} | R Documentation |
This is a year-month-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 class 'clock_year_month_day' calendar_start(x, precision) ## S3 method for class 'clock_year_month_day' calendar_end(x, precision)

A year-month-day vector. |

One of:

x
at the same precision, but with some components altered to be
at the boundary value.
# Hour precision x <- year_month_day(2019, 2:4, 5, 6) x # Compute the start of the month calendar_start(x, "month") # Or the end of the month, notice that the hour value is adjusted as well calendar_end(x, "month") # Compare that with just setting the day of the month to `"last"`, which # doesn't adjust any other components set_day(x, "last") # You can't compute the start / end at a more precise precision than # the input is at try(calendar_start(x, "second"))
