calendar-boundary {clock} | R Documentation |
calendar_start()
computes the start of a calendar at a particular
precision
, such as the "start of the quarter".
calendar_end()
computes the end of a calendar at a particular
precision
, such as the "end of the month".
For both calendar_start()
and calendar_end()
, the precision of x
is
always retained.
Each calendar has its own help page describing the precisions that you can compute a boundary at:
calendar_start(x, precision)
calendar_end(x, precision)
x |
A calendar vector. |
precision |
A precision. Allowed precisions are dependent on the calendar used. |
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")
