# Practical Data Science With R

John Mount and I are proud to present our book, *Practical Data Science with R, 2nd Edition*. This is the book for you if you are a data scientist, want to be a data scientist, work with data scientists, or hire data scientists.

Our goal is to present data science from a pragmatic, practice-oriented viewpoint. The book will complement other analytics, statistics, machine learning, data science and R books with the following features:

This book teaches you how to work as a data scientist. Learn how important listening, collaboration, honest presentation and iteration are to what we do.

The key emphasis of the book is process: collecting requirements, loading data, examining data, building models, validating models, documenting and deploying models to production.

We provide over 10 significant example datasets, and demonstrate the concepts that we discuss with fully worked exercises using standard R methods. We feel that this approach allows us to illustrate what we really want to teach and to demonstrate all the preparatory steps necessary to any real-world project.

This book is scrupulously correct on statistics, but presents topics in the context and order a practitioner worries about them. We emphasize machine learning and prediction over the use of summary statistics.
