R: Boundaries: year-quarter-day

year-quarter-day-boundary {clock} | R Documentation

## Boundaries: year-quarter-day

### Description

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`.

### Usage

    ## S3 method for class 'clock_year_quarter_day'
    calendar_start(x, precision)

    ## S3 method for class '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

    # Compute the last moment of the fiscal quarter
    calendar_end(x, "quarter")

    # Compare that to just setting the day to `"last"`,
    # which doesn't affect the other components
    set_day(x, "last")

    # Compute the start of the fiscal year
    calendar_start(x, "year")

    as_date(calendar_start(x, "year"))
