Just to add to what Steve has said: write it in R, then profile, then just convert the slowest part to C++. That is the beauty of Rcpp/inline: you can do it one function at a time. (Or if you have a cluster, look at parallel R options ;-) Also, you wrote "I need to create functions"; do you already have the R version? If not, and given that you are an R expert, write the R version first. Don't assume C++ will be quicker. Inexpertly written C++ can be slower than the same code in interpreted languages.
