Hi -

I am trying to create an rcpp data frame with more than 20 columns. I get a compile error that it cannot find the matching function for call to Rcpp::DataFrame::create.
When I try to create it for 20 columns, it works fine. Is 20 columns the maximum number that you can use in the Rcpp::DataFrame::create?
If you have any suggestions regarding this, that would be great.

Thanks,
Andrew Bierbryer

Yes.  

Per an auto-generated set of constructors which we once expanded from 6 (as I
recall) to 20.

Create a local header file with 21, 22, 23, ... \infty arguments as you need it.
