Hey all who have responded to this post. I am a newbie to ANOVA analysis in
R, and let me tell you- resources for us learners are scant, horrible,
unclear, imprecise.. in other words.. the worst ever. So advice like "go
look it up" in your "classical" textbook or on google is not helpful at all.
I am scouring posts like these to try to find some kind soul who not only
understands the basics, but is willing to help us new folk out.. sadly..
here is not the place.

My experience is the opposite -- the web is filled with introductory
statistics material, some of it quite good. If you google for
"introduction to anova textbook" the first hit seems to give exactly
what you are asking for. The fifth one down the list also looks good
(http://vassarstats.net/textbook/ch13pt1.html). And that's just what
you get for free! If you want more you can buy a textbook. I don't
understand why you are reluctant to take this advice, or why you think
someone here is going to be able to explain it better than a good
textbook will.

Best,
Ista

Or look for A handbook of Statistical Analyses using R. (Everitt and Holhorn) available on line in pdf format.

Although it would be rude to tell you to go look it up yourself, you do not 
pose a specific problem so it is impossible to provide a specific answer. 
This is why there is a posting guide requesting  that you do so.  Further, 
you pose your question in a rather rude way which makes the list readers 
less likely to want to help you!

I myself am a user of statistics, not a statistician, but I firmly believe 
that we must understand the statistics we use.  That means you won't get a 
prescriptive answer from me without a focused question.

What made a huge difference for me in understanding ANOVA in R was John 
Fox's book, An R and S-Plus Companion to Applied Regression Analysis.  It 
really helps understand the R way of doing things.  Another helpful resource 
for some of the classical ANOVA models is Murray Logan's, Biostatistical 
Design and Analysis Using R: A Practical Guide .  It is an R resource that 
follows the Quinn and Keogh Experimental and Data Analysis text with plenty 
of R code and examples.  The only downside to the latter text is that it has 
numerous typos that seem to have escaped the editing process.  If you 
haven't already, I'd check these two resources.
