I tried another approach, and this one was also futile.
try{
int size = argTypes.getColumnCount();
std::vector inputVectors;
inputVectors.reserve(3);
StringVector nameVec(size);
NumericVector lenVec(size) ;
NumericVector scaleVec(size) ;

I tried the code that you suggested on The R prompt and it worked as
expected. However the same piece of code doesn't work in my C++ app.
try{
IntegerVector v = IntegerVector::create(1,2,3);
std::vector s(3);
s[0] = "a";
s[1] = "a";
s[2] = "a";
