The purpose of this portion was to offer an introduction to Rcpp. One of many selling characteristics of Rcpp is that there is a great deal of documentation accessible.
is productive Except you are able to promptly redo it. Documenting your code inside dynamic documents in this manner makes sure that Investigation might be quickly re-operate.
Within this chapter we assume that you have already got nicely-developed code that is definitely experienced conceptually and continues to be tried out and examined. Now you need to enhance this code, but not prematurely. The chapter is organised as follows. First we start with basic hints and suggestions about optimising foundation R code.
