iso-year-week-day-count-between {clock} | R Documentation

## Counting: iso-year-week-day

### Description

This is an iso-year-week-day method for the `calendar_count_between()` generic. It counts the number of `precision` units between `start` and `end` (i.e., the number of ISO years).

### Usage

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

### Arguments

`start, end` | `[clock_iso_year_week_day]` A pair of iso-year-week-day vectors. These will be recycled to their common size.
`precision` | `[character(1)]` One of: `"year"`
`...` | 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 ISO years between two dates
    x <- iso_year_week_day(2001, 1, 2)
    y <- iso_year_week_day(2021, 1, c(1, 3))
    calendar_count_between(x, y, "year")
