hi. i really need help using this program. computer language is a foreign language to me, and thus, i cannot make heads nor tails of the user manuals from the website. i need to locate step-by-step examples of simple problems such as "graph f(x)+g(x) and f(g(x)) for the domain 0<x<2" and "graph 2H(x), H(x)+1, H(x+1)" i do know how to define the functions, but that's it. is there any help you could provide me? i would appreciate some help asap. thank you very much erin leisz

Here you learn R along some basic statistical analyses.

Hope this helps.

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. Eric Kostello On Mon, 20 Sep 2004 23:10:59 -0500, "Erin L.
