seq.clock_year_quarter_day {clock} R Documentation

## Sequences: year-quarter-day

### Description

This is a year-quarter-day method for the seq() generic.

Sequences can only be generated for "year" and "quarter" precision year-quarter-day vectors.

When calling seq(), exactly two of the following must be specified:

• to

• by

• Either length.out or along.with

### Usage

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


### Arguments

 from ⁠[clock_year_quarter_day(1)]⁠ A "year" or "quarter" precision year-quarter-day to start the sequence from. from is always included in the result. to ⁠[clock_year_quarter_day(1) / NULL]⁠ A "year" or "quarter" precision year-quarter-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 to < from, then by must be positive. If to > from, then by must be negative. 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.

### Value

A sequence with the type of from.

### Examples

# Quarterly sequence
x <- seq(year_quarter_day(2020, 1), year_quarter_day(2026, 3), by = 2)
x

# Which we can then set the day of the quarter of
set_day(x, "last")
