Jared Wilber posted this great walkthrough where he codes a simple R data pipeline using purrr and tidyr to train a large variety of models and methods on the same base data, all in a non-repetitive, reproducible, clean, and thus tidy fashion. Really impressive workflow!

Learning Functional Programming & purrr
The R for Data Science (R4DS) book by Hadley Wickham is a definite must-read for every R programmer. Amongst others, the power of functional programming is explained in it very well in the chapter on Iteration. I wrote about functional programming before, but I recently re-read the R4DS book section after coming across some new valuable…
tidyverse 101: Simplifying life for useRs
Hadley Wickham‘s tidyverse has improved the workflow of analysts / data scientists, makes coding errors less likely and code more transparent. You’ve got to love the figure below, representing a simplified workflow of the average analysis project. The tidyverse provides assistance in each of the stages. Various packages provide functionality to perform analytical tasks more effectively, in…
