[Rcpp-devel] Using older RInside/Rcpp without operator?

I use RInside and Rcpp packages to make a few R calls from C++ for a
bioinformatics project I'm doing. I'm trying to get my code working on a
big cluster on campus to speed up the analysis I need to do on real data now
that my methodological development is done. The admins for that cluster
were only able to get RInside 0.2.1, and I think Rcpp 0.7.9 (maybe 0.7.8?)
compiled properly. This has meant that operator has disappeared.
I was setting up my R instance with the standard:
RInside R(0, NULL);
And then was creating Rcpp::NumericVector instances, filling them, then
R["var.name"] = my_numeric_vector;
How do I accomplish this assignment in the older versions? I've been
looking through the header files at the assign functions, but:
doesn't work, as there are only assign functions defined to take standard
STL vectors as the thing to be assigned to the given variable name in the R
instance. Do I have to rewrite the code so the NumericVector instances are
just std::vector<double> instances? Is there some other function other than
the assign functions that I can use? Is there a built in function in
NumericVector to cast it to a STL vector of doubles?
I really appreciate the vast work you've put into this package. It's saved
my butt a few times!
