R: Counting: year-quarter-day

year-quarter-day-count-between {clock} | R Documentation

## Counting: year-quarter-day

### Description

This is a year-quarter-day method for the `calendar_count_between()` generic. It counts the number of `precision` units between `start` and `end` (i.e., the number of years or quarters).

### Usage

    ## S3 method for class 'clock_year_quarter_day'
    calendar_count_between(start, end, precision, ..., n = 1L)

### Arguments

`start, end` | `[clock_year_quarter_day]` A pair of year-quarter-day vectors. These will be recycled to their common size.
`precision` | `[character(1)]` One of: `"year"` `"quarter"`
`...` | These dots are for future extensions and must be empty.
`n` | `[positive integer(1)]` A single positive integer specifying a multiple of `precision` to use.

### Value

An integer representing the number of `precision` units between `start` and `end`.

### Examples

    # Compute the number of whole quarters between two dates
    x <- year_quarter_day(2020, 3, 91)
    y <- year_quarter_day(2025, 4, c(90, 92))
    calendar_count_between(x, y, "quarter")

    # Note that this is not always the same as the number of whole 3 month
    # periods between two dates
    x <- as_year_month_day(x)
    y <- as_year_month_day(y)
    calendar_count_between(x, y, "month", n = 3)
