e.g.
SEXP La_DGE_dc(SEXP A)

SEXP aa = PROTECT(duplicate(A));

S4 classes and C
...o 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/slide
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.
