[Rcpp-devel] integer and numeric vector

[Romain François]

Hello,

I've commited Rcpp::IntegerVector and Rcpp::NumericVector. see the unit 
tests for more examples, but here's an example:

NumericVector x = {0.0,1.0,2.0,3.0} ; // this needs GCC >= 4.4
for( int i=0; i<x.size(); i++) x[i] = x[i]*2 ;
return x ;',

other constructors are available so that the class is usable before 4.4:

NumericVector x(10) ; // allocate an numeric vector of 10 elements (uses 
Rf_allocVector( REALSXP, 10 )

or the NumericVector(SEXP) which simply wraps up the SEXP into an object.

Romain
