R in a Nutshell: A Desktop Quick Reference Review

R in a Nutshell: A Desktop Quick Reference
Average Reviews:

(More customer reviews)
'R in a Nutshell' is the essential introductory book on R. Do not try to learn R without it.
I made two attempts to learn R before purchasing this book. In both previous attempts, I had to abort and use another tool to solve my problem because it was taking me too long to accomplish very simple things in R.
The reason R is hard to learn is that its documentation is organized for statisticians that already know R, but have forgotten a detail or two. There are a few other books on learning R, but they are setup like a college course - complete the entire book and THEN you can actually accomplish something.
R in a Nutshell allows you to get working immediately. Simply lookup what you need to do. The firsts thing I did was load a file and make a histogram. I found that stuff in the section on "Loading Data" and the section on charts. In no time I was making stacked area charts for cohorts. Now R is an essential tool for me - and I haven't even taken the time to learn it well! With this book, I don't have to. I can learn as I go. So I actually use R.
Do not R without it.

Damned Lies and Statistics: Untangling Numbers from the Media, Politicians, and Activists Review

Damned Lies and Statistics: Untangling Numbers from the Media, Politicians, and Activists

Are ten percent of Americans gay? Is the white male in the work force rapidly becoming a minority? Are 150,000 young American women dying each year from anorexia?
Joel Best clearly answers "no" to each of these three questions and, more importantly, shows why many people would say "yes". His point is that descriptive statistics are the product of a social activity, not just a representation of society. Social advocacy causes people to collect the data that they feel will best support their preconceived notions: They talk to unrepresentative groups. They start to collect new measures and then wonder why the "statistics" have grown since ten years earlier (when they weren't much -- if at all -- measured). They multiply erroneous assumptions. They mutate data. And the press and other publications carry the mutations forward.
This book offers plenty of illustrations of intentions run amok. Many of the reports provide useful information for a classroom lecture on the need to discern if a person is "speaking rot", as Harold Macmillan once said was the primary purpose of an education.
A good, crisp 171 pages in length, it is absent discussion of the more difficult inferential statistics and, as a result, it is easy to understand by the lay person.
