See [this discussion](https://rdotnet.codeplex.com/discussions/539844).
Started a unit test; now that function calls with dotted pairlists works, calling the data frame function is much easier.
Feature is already implemented; needs:
- Unit tests (incl. odd cases, different vector lengths etc.)
- Assess the convenience of the API design for data frame creation.
- Support passing already existing R vectors (Actually probably already do, but may be convenient to avoid a full mem copy to better scale up to large data sets)
