| | 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.

5. Never ever send images of data when someone asks for example data.

Dirk
