| First, few preliminary remarks before answering your question.
| 1. Just like every one asking for assistance, your should provide a minimal reproducible example.
| 2. Before asking about Rcpp issue, it would be reasonable if you test your comps() function in R,
| to be sure that the problem is not in comps() itself (and yes, there is a problem in comps(), cf. hereafter)
| 3. It is counter-intelligent to use Rcpp just for calling an R function. Sometimes such calling is
| unavoidable but doing _only_ this is a waste of time. Simply call your function directly from R.
| Main interest of Rcpp is to easily interface functions written in C++ (which are usually
| much faster then their counterparts in R) with R session.

4. Do not crosspost to StackOverflow (or other venues) _and_ post here.
