C++ (Cpp) CharacterMatrix::nrow Examples

Example #1

File: obsHet.cpp Project: StuntsPT/diveRsity

// [[Rcpp::export]]
double obsHet(CharacterMatrix in_mat) {
  
  //CharacterVector new_mat = in_mat(_,1) ;
  
  int n = in_mat.nrow() ;
  double total = 0 ;
  double ns = 0 ;
  
  for(int i = 0; i < n; i++){
    
    CharacterVector tst = in_mat(i,_) ;
    LogicalVector id = is_na(tst) ;
    
    if(tst[0] != tst[1]){
      total += 1 ;
    }
    
    if(!id[0]) {
      ns += 1 ;
    }
    
  }
  
  return total/ns ;
}

Example #2

File: HybRIDScore.cpp Project: gitter-badger/HybRIDS

// [[Rcpp::export]]
LogicalVector sequenceChecker_cpp(CharacterMatrix x){
  int nc = x.ncol() ;
  CharacterVector ns(x.nrow());
  CharacterVector Ns(x.nrow());
  std::fill(ns.begin(), ns.end(), "n");
  std::fill(Ns.begin(), Ns.end(), "N");
  LogicalVector out(nc);
  for(int i=0; i < nc; i++){
    out[i] = is_false(any(x(_,i) == Ns)) && is_false(any(x(_,i) == ns)) && unique(x(_,i)).size() != 1;
  }
  return out;
}
