Source: R/s3-integer64.R
opts_integer64.Rd

These options will be used on objects of class 'integer64'.

Usage

opts_integer64(constructor = c("as.integer64", "next", "double"), ...)

Arguments

constructor

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

...

Additional options used by user defined constructors through the opts object

Value

An object of class <constructive_options/constructive_options_integer64>

Details

Depending on constructor, we construct the object as follows:

  • "as.integer64" (default): Build the object using as.integer64() 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.

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

We don't recommend the "next" and "double" constructors for this class as they give incorrect results on negative or NA "integer64" objects due to some quirks in the implementation of the 'bit64' package.
