opts_S4: Constructive options for class 'S4'

In constructive: Display Idiomatic Code to Construct Most R Objects

Constructive options for class 'S4'

Description

These options will be used on objects of class 'S4'.

Usage

opts_S4(constructor = c("new", "prototype"), ...)

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

Details

Depending on constructor, we construct the object as follows:

• "new" (default): We build the function using new() if possible. If the class has a "initialize" method we have no practical way to reverse-engineer the inputs so we fall back to the "prototype" constructor

• "prototype" : We start from getClass("S4")@prototype and add attributes.

Value

An object of class <constructive_options/constructive_options_S4>
