Subject: [Rd] S4 classes and C
Is there any good source of information on how S4 classes (and methods)
work from C?
E.g., for reading
how to read a slot value
how to invoke a method
how to test if you have an s4 object
For writing, how to make a new instance of an S4 object.
I've found scattered hints in the archive, including a link to a talk on
this subject "I am using C code to create an S4 object based on Douglas
Bates's example in his lecture notes on
but the link is no longer good (after putting it all on one line).
"Writing R Extensions" (2.3.0 version) makes no reference to this topic
that I can see.
