R help - Jun 2009 - pass a vector to C++

Hi,

Does anyone know how to pass a vector of strings, for example
"c("1", "2", "3") to a C++ function? Should
the input argument to the C++ function be vector<string>*?

Thanks a lot!

For the basic mechanics of making R and C/C++ talk, see the 'R
Extensions'
manual that came with your copy of R, or find it on CRAN.

For a higher level of abstraction, you may find my Rcpp package (on CRAN,
r-forge and at http://dirk.eddelbuettel.com/code/rcpp.html) useful.  It does
indeed allow you to use c("1", "2", "3") as
vector<std::string> (after one
cast from RcppStringVector).
