Generate Sequences of Week Numbers

Generate regular sequences of weeknumber values.

Usage

# S3 method for class 'weeknumber'
seq(from, to, by, length.out = NULL, along.with = NULL, ...)

Arguments

from

A length-1 weeknumber vector giving the start of the sequence.

to

A length-1 weeknumber vector giving the end of the sequence.

by

A length-1 numeric week increment.

length.out

Desired length of the output sequence.

along.with

Take the length from this object.

...

Unused.

Value

A weeknumber vector.

Details

This method mirrors classed seq() methods such as seq.Date(). Supply from and to, or one endpoint together with length.out/along.with. When by is supplied, it should be a single numeric week increment.

Examples

seq(make_weeknumber(2000, 1), make_weeknumber(2000, 9), by = 2)
#> <weeknumber[5]>
#> [1] 2000-W01 2000-W03 2000-W05 2000-W07 2000-W09
seq(from = make_weeknumber(2000, 1), length.out = 3, by = 1)
#> <weeknumber[3]>
#> [1] 2000-W01 2000-W02 2000-W03
