Interactive Web-Based Data Visualization with R plotly and shiny

I'm still in the early part with 0.000...0 concern about this Book. Printing is color and paper quality is awesome.

If you write R apps for a living this book will save you a ton of time and many headaches. Reads like a great novel - I read it from cover to cover, typing most of the examples into RStudio (I know I could have copied from online version, but I learn by typing :)) in a week and was amazed at how well Carson Sievert understands scientific programming and graphics and how well he can teach it. There is a fair share of typos (p. 67 is the best) and code which does not work right away, but it does not take away from the book. This book is pure gold!
