Data frame support has been added to the package RcppTemplate 4.0, a template/class library that facilitates the use of C++ libraries from R.

On the C++ side the code might look something like:

RcppFrame frame(fp); // Here fp is the input SEXP corresponding to an R data frame.
vector<vector<ColDatum> > table = frame.getTableData();

level = table[row][col].getFactorLevel(); name = table[row][col].getFactorName();

Thanks to Hin-Tak Leung and other users of this mailing list for helpful comments.

The RcppTemplate package also contains detailed instructions on using MinGW and MS Visual C++ under Windows.
