Constructive options for class 'POSIXct'

Source: R/s3-POSIXct.R
opts_POSIXct.Rd

These options will be used on objects of class 'POSIXct'.

Usage

opts_POSIXct(
  constructor = c("as.POSIXct", ".POSIXct", "as_datetime", "as.POSIXct.numeric",
    "as_datetime.numeric", "next", "atomic"),
  ...,
  origin = "1970-01-01"
)

Arguments

constructor

String. Name of the function used to construct the object, see Details section.

...

Should not be used. Forces passing arguments by name.

origin

Origin to be used, ignored when irrelevant.

Value

An object of class <constructive_options/constructive_options_POSIXct>

Details

Depending on constructor, we construct the object as follows:

  • "as.POSIXct" (default): Build the object using a as.POSIXct() call on a character vector.

  • ".POSIXct" : Build the object using a .POSIXct() call on a numeric vector.

  • "as_datetime" : Build the object using a lubridate::as_datetime() call on a character vector.

  • "next" : Use the constructor for the next supported class. Call .class2() on the object to see in which order the methods will be tried.

  • "atomic" : We define as an atomic vector and repair attributes.

If the data is not appropriate for a constructor we fall back to another one appropriately. In particulat corrupted POSIXct objects such as those defined on top of integers (or worse) are all constructed with the ".POSIXct" constructor.
