[R] can't understand "R"

Krause and Olson's "The Basics of S-PLUS" offers a very, very gentle
introduction to S-PLUS and R. (How gentle? It even explains how to
use a mouse!) It does not attempt to teach statistics or data analysis,
although the reader will certainly learn something by being exposed
to well-designed examples. "The Basics" teaches by example and
then explains more abstract aspects of what you have done. Because 
the step-by-step instructions are very clear, this works well.

I would not teach an S-PLUS or R based data analytic class without
at least placing it on the recommended reading list. I believe it
takes the place of nearly all material typically place on "tip
sheets." Nevertheless, it gets all the way through to writing simple
scripts and programs.

For a reader already familiar with script-based analysis in either
R or S-PLUS this book will not offer much value. For the reader
who needs to move beyond "point-and-click" into more solid data
analytic skills, I strongly recommend it.

Disclaimer: this is based on my review of the second edition, so
updates or corrections for the third edition may be in order.
