R: Arithmetic: year-quarter-day

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

## Arithmetic: year-quarter-day

### Description

These are year-quarter-day methods for the arithmetic generics.

- `add_years()`

- `add_quarters()`

Notably, you cannot add days to a year-quarter-day. For day-based arithmetic, first convert to a time point with `as_naive_time()` or `as_sys_time()`.

### Usage

    ## S3 method for class 'clock_year_quarter_day'
    add_years(x, n, ...)

    ## S3 method for class 'clock_year_quarter_day'
    add_quarters(x, n, ...)

### Arguments

`x` | `[clock_year_quarter_day]` A year-quarter-day vector.
`n` | `[integer / clock_duration]` An integer vector to be converted to a duration, or a duration corresponding to the arithmetic function being used. This corresponds to the number of duration units to add. `n` may be negative to subtract units of duration.
`...` | These dots are for future extensions and must be empty.

### Details

`x` and `n` are recycled against each other.

### Value

`x` after performing the arithmetic.

### Examples

    x <- year_quarter_day(2019, 1:3)
    x

    add_quarters(x, 2)

    # Make the fiscal year start in March
    y <- year_quarter_day(2019, 1:2, 1, start = 3)
    y

    add_quarters(y, 1)

    # What year-month-day does this correspond to?
    # Note that the fiscal year doesn't necessarily align with the Gregorian
    # year!
    as_year_month_day(add_quarters(y, 1))
