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

add_years(x, n, ...)
x |
A iso-year-week-day vector. |
n |
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. |
... |
These dots are for future extensions and must be empty. |
x
and n
are recycled against each other using
tidyverse recycling rules.
x
after performing the arithmetic.
x <- iso_year_week_day(2019, 1, 1)
add_years(x, 1:2)
