I am trying to update a package from 2010 to the new standards, including
adding a NAMESPACE file. The package has S4 classes, and I'm having some
trouble interpreting the manual.
Suppose I have
setClass("MyClass", .....)
MyClass <- function(a, b, c) {...} # constructor
and various methods for the class
Assuming I want to make the class and everything associated user-visible, I must
exportClass(MyClass)
Do I need to
export(MyClass)
so the constructor is visible?
Do I need to
exportMethods()
for the methods of that class?
I take it that if the class uses a name from elsewhere in the system, e.g., it
has a "print" method, I must import that too. Or is it that I only need to
import generics that are not in the base package?
