[R] Two Way ANOVA

[Daniel Malter]

Hi,

your post is hardly readable because it is so spread out over several pages.
Can you repost it? 

Besides that I do not understand your question fully. The y is your
dependent variable and as it looks the A*B would be Sulfur*Nitrogen if these
are your variable names.

You can also take a look at the manuals that are available for free on cran.
Most of them deal with ANOVA I would say.

Cheers,
Daniel

Betreff: [R] Two Way ANOVA

First time using, the mailing list and I'm somewhat new to R, so excuse me
if I do anything wrong.

I was wondering how I would set up a two way ANOVA for the following data:


      
      Nitrogen
  (0)
       
      Nitrogen
  (20)
       
       
         
       
      (cell
  means)
       
      (cell
  means)
      [Sulfur means]
        Sulfur (0)
      4.48
       
      5.76

        Sulfur (3)
      4.70
       
      7.01
       
       
         
      4.65
      (4.64)

But what would I set for A, B and y?
