Floor methods for date objects

Source: R/date.R
floor_month.Rd

floor_month() and floor_week() are simple wrappers around lubridate::floor_date() that round down to the first day of the month or week.

floor_days() rounds down to the nearest n-day increment. Floors are defined relative to the earliest date in x, unless a different start date is passed to start. Default behavior differs from lubridate::floor_date(x, unit = "{n} days"), which "resets" the floor to the first of the month with each month. lubridate-like behavior can be achieved by setting reset_monthly = TRUE.

Usage

floor_month(x)

floor_week(x, week_start = getOption("lubridate.week.start", 7))

floor_days(x, n = 1L, start = min(x, na.rm = TRUE), reset_monthly = FALSE)
