thx, dirk. first, apologies for multiposting earlier. I thought it did
not allow me to post from my non-registered email address. second,
apologies for the private email. I wasn't expecting any answers. just
wanted to help with some feedback. I will buy your Rcpp book when it comes
out.
I think you are correct that modules are too tough for me. heck, I don't
even write R packages. I am just an end user. I would have to learn how
to write and build those first. so, I think I will want to go the accessor
function route. can cppFunction() allow me to define structures? I am
just trying something super-simple here:
library( Rcpp )
cppFunction('
struct Silly {
double *v; int k;
};
void hello(int i) { printf("hello, world\n"); }
')
cat("Compiled OK\n")
but it fails, both on the printf and on the structure definition. I am
wondering whether cppFunction can just handle single functions and without
quotation marks.
regards,
/iaw
