I'm trying to figure this out with "Writing R Extensions" but there's not a
lot of detail on this issue.
I want to write a (very simple really) C external that will be able to take
"..." as an argument.
(It's for optimizing a function that may have several parameters besides the
ones being optimized.)
I got the "showArgs" code (from R-exts) to compile and install, but it only
gives me error messages when I run it. I think I'm supposed to pass it
different arguments from what I'm doing, but I have no idea which ones.
What exactly are CAR, CDR, and CADR anyway? Why did the R development team
choose this very un-C-like set of commands? They are not explained much in
R-exts.
Thanks in advance for any info.
