R help - Apr 2017 - New free book to help learn the basics of data analysis with R in a single day

I have written a book to help new users of R, who are familiar with at 
least one programming other
than R, learn the basics of data analysis in a single day. The book is 
free and released under the
most non-restrictive of the creative commons licenses. There is R code 
that accompanies the book.

The book is available in eReader formats on Smashwords
(https://www.smashwords.com/books/view/713592) and Barnes and Noble
(http://www.barnesandnoble.com/w/just-enough-r-sivakumaran-raman/1126163491). 
A pretty-printed PDF
is downloadable from here:

Feedback is welcome. I hope the book will be a useful resource for newbies.

Thanks,
Siv Raman
