Sequence

Source: R/seq.R
dtt_seq.Rd

Creates a date/time sequence vector. from and to are first floored and then a sequence is created by units. If length_out is defined then that number of units are added to from.

Usage

dtt_seq(from, to, units, length_out = NULL, ...)

# S3 method for class 'Date'
dtt_seq(from, to = from, units = "days", length_out = NULL, ...)

# S3 method for class 'POSIXct'
dtt_seq(from, to = from, units = "seconds", length_out = NULL, ...)

# S3 method for class 'hms'
dtt_seq(
  from,
  to = from,
  units = "seconds",
  length_out = NULL,
  wrap = TRUE,
  ...
)

Arguments

from

A date/time scalar of the start.

to

A date/time scalar of the end.

units

A string of the time units. The possible values are "secs", "minutes", "hours", "days" or "weeks".

length_out

An integer of the number of units from from.

...

Unused.

wrap

A flag specifying whether to wrap hms vectors from 23:59:59 to 00:00:00

Value

The date/time vector.

Methods (by class)

  • dtt_seq(Date): Create a Date sequence vector

  • dtt_seq(POSIXct): Create a POSIXct sequence vector

  • dtt_seq(hms): Create a hms sequence vector

Examples

dtt_seq(as.Date("2001-01-01"), as.Date("2001-01-05"))
#> [1] "2001-01-01" "2001-01-02" "2001-01-03" "2001-01-04" "2001-01-05"
