This is a iso-year-week-day method for the `seq()`

generic.

Sequences can only be generated for `"year"`

precision
iso-year-week-day vectors. If you need to generate week-based sequences,
you'll have to convert to a time point first.

When calling `seq()`

, exactly two of the following must be specified:

`to`

`by`

Either

`length.out`

or`along.with`

## Usage

```
# S3 method for clock_iso_year_week_day
seq(from, to = NULL, by = NULL, length.out = NULL, along.with = NULL, ...)
```

## Arguments

- from
`[clock_iso_year_week_day(1)]`

A

`"year"`

precision iso-year-week-day to start the sequence from.`from`

is always included in the result.- to
`[clock_iso_year_week_day(1) / NULL]`

A

`"year"`

precision iso-year-week-day to stop the sequence at.`to`

is cast to the type of`from`

.`to`

is only included in the result if the resulting sequence divides the distance between`from`

and`to`

exactly.- by
`[integer(1) / clock_duration(1) / NULL]`

The unit to increment the sequence by.

If

`by`

is an integer, it is transformed into a duration with the precision of`from`

.If

`by`

is a duration, it is cast to the type of`from`

.- length.out
`[positive integer(1) / NULL]`

The length of the resulting sequence.

If specified,

`along.with`

must be`NULL`

.- along.with
`[vector / NULL]`

A vector who's length determines the length of the resulting sequence.

Equivalent to

`length.out = vec_size(along.with)`

.If specified,

`length.out`

must be`NULL`

.- ...
These dots are for future extensions and must be empty.

## Examples

```
# Yearly sequence
x <- seq(iso_year_week_day(2020), iso_year_week_day(2026), by = 2)
x
#> <iso_year_week_day<year>[4]>
#> [1] "2020" "2022" "2024" "2026"
# Which we can then set the week of.
# Some years have 53 ISO weeks, some have 52.
set_week(x, "last")
#> <iso_year_week_day<week>[4]>
#> [1] "2020-W53" "2022-W52" "2024-W52" "2026-W53"
