iso-year-week-day-arithmetic {clock} R Documentation

## Arithmetic: iso-year-week-day

### Description

These are iso-year-week-day methods for the arithmetic generics.

• add_years()

You cannot add weeks or days to an iso-year-week-day calendar. Adding days is much more efficiently done by converting to a time point first by using as_naive_time() or as_sys_time(). Adding weeks is equally as efficient as adding 7 days. Additionally, adding weeks to an invalid iso-year-week object containing iso_year_week_day(2019, 53) would be undefined, as the 53rd ISO week of 2019 doesn't exist to begin with.

### Usage

## S3 method for class 'clock_iso_year_week_day'


### Arguments

 x ⁠[clock_iso_year_week_day]⁠ A iso-year-week-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 <- iso_year_week_day(2019, 1, 1)
