This book focuses is on data science. It includes plenty of actual examples of the typical data processing and data presentations required of a professional data scientist.

As a practitioner, the author brings a practical view on the topic, with a very hands-on oriented presentation that will be particularly useful to other practitioners. The book also concentrates on the current generation of R packages that have added considerable capability to R, including Hadley Wickam's suite of packages, such as tidyr, dplyr, lubridate, stringr, and ggplot2.
