> I have also added methods to deal with S4 objects (in the RObject class
> since an S4 object can be of any SEXP type): hasSlot, isS4 and slot.

> For GenericVector and CharacterVector, I have implemented the proxy
> pattern as described in item 30 of More Effective C++, so that we can do :
>
> CharacterVector x(10) ; /* create a character vector of 10 strings */
> x[0] ; /* gets the first element */
> x[1] = "foo" ; /* sets the second element */
>
> List y(3) ;
> y[0] = 1 ; /* 1 gets wrap()'ed into a IntegerVector */
> y[1] = "foo" ; /* foo gets wrap()'ed into a CharacterVector */
> y[2] = false ; /* false gets wrap()'ed into a LogicalVector */
>
> As usual, many examples have been added in the unit tests.
