Constructive options for R_system_version

Depending on constructor, we construct the object as follows:

• "R_system_version" : We use R_system_version()

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

• "list" : We define as a list and repair attributes

Usage

opts_R_system_version(constructor = c("R_system_version", "next", "list"), ...)

Arguments

constructor

String. Name of the function used to construct the object.

...

Additional options used by user defined constructors through the opts object

An object of class <constructive_options/constructive_options_R_system_version>
