useR! 2014 -- Martin Mächler - Good Practices in R Programming


At the first useR! meeting in Vienna in 2004, I had presented seven guidelines for good R programming practice I called "rules". Revisiting, I will ask how much has changed - or not. Namespaces have brought even more justification for emphasizing functions as the main ingredients of much of good R code. We have more and better tools for reproducible research and data analysis nowadays, and I'll touch on some consequences I see for useR's code organization. As some of it has been my specialty within R Core, we'll also look into some aspects of a generalized FAQ 7.31 and what every programmeR should know about computer arithmetic.
