Dear R People:
I'm not sure if I should ask this here or in Rcpp,
Why is this related to Rcpp?
but I thought I'd
start here first.
If I'm writing a C program, when do I know to use SEXP vs. int or float, please?
For very short:
If you want keep some things internal to your C code, use int etc. , but
if it makes sense to use R objects (e.g. because you return things or
make use of otehr R functionality), use SEXP objects. If the latter, you
already decided to use the .Call() interface.
There is more in Writing R Extensions.

Thanks,
