H. Wickham (2014a) presents an incredibly readable chapter on Rcpp that goes right into a bit more element than this part;

At the time a project overview has been devised and saved, in mind (for small projects, for those who belief that as storage medium!) or penned, a prepare with a time-line is often drawn-up. The up-to-day visualisation of the approach can be a powerful reminder to by yourself and collaborators of development around the project so far. A lot more importantly the timeline delivers an overview of what really should be performed up coming.

To beat this inefficiency inside the documentation of R outputs the R Markdown framework was developed. Employed along side the knitr bundle, We have now the opportunity to
