Constructive options for class 'factor' — opts

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

Usage

opts_factor(
  constructor = c("factor", "as_factor", "new_factor", "next", "integer"),
  ...
)

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

An object of class <constructive_options/constructive_options_factor>

Depending on constructor, we construct the object as follows:

"factor" (default): Build the object using factor(), levels won't be defined explicitly if they are in alphabetical order (locale dependent!)
"as_factor" : Build the object using forcats::as_factor() whenever possible, i.e. when levels are defined in order of appearance in the vector. Otherwise falls back to "factor" constructor.
"new_factor" : Build the object using vctrs::new_factor(). Levels are always defined explicitly.
"next" : Use the constructor for the next supported class. Call .class2() on the object to see in which order the methods will be tried.
"integer" : We define as an integer vector and repair attributes.
