Sequences: date and date-time

Description

date_seq() generates a date (Date) or date-time (POSIXct/POSIXlt) sequence.

There are separate help pages for generating sequences for dates and date-times:

• dates (Date)

• date-times (POSIXct/POSIXlt)

Usage

date_seq(from, ..., to = NULL, by = NULL, total_size = NULL)

Arguments

from	⁠[Date(1) / POSIXct(1) / POSIXlt(1)]⁠ A date or date-time to start the sequence from.
...	These dots are for future extensions and must be empty.
to	⁠[Date(1) / POSIXct(1) / POSIXlt(1) / NULL]⁠ A date or date-time to stop the sequence at. 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.
total_size	⁠[positive integer(1) / NULL]⁠ The size of the resulting sequence. If specified alongside to, this must generate a non-fractional sequence between from and to.

Value

A date or date-time vector.

Examples

# See method specific documentation for more examples

x <- as.Date("2019-01-01")
date_seq(x, by = duration_months(2), total_size = 20)
