Hi,
As other have said, it's very difficult to help you without an example
+ code to know what you are talking about.
That having been said, it seems as if you are just getting your feet
wet in this R <--> C bridge, and I'd recommend you checkout the "Rcpp"
and "inline" package to help make your life a lot easier ...
