[Rd] S4 classes and C

[McGehee, Robert]

I believe the paper on which those lecture notes were based can be found
here:

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
<http://www.ci.tuwien.ac.at/Conferences/DSC-2003/Tutorials/RExtensions/s
lide
s.pdf>"
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.
