Hi listers, 
 
I've been studying anova and at the book of Kuehl at the chapter
about split-plot there is a experiment with the results... I am trying to
understand the experiments and make the code in order to obtain the
results... But there is something that I didn't understand yet...
I have a split-plot design (2 blocks) with two facteurs, one
facteur has 4 treatments and the other facteur is a measure
taken in three years...
I organize my data set as:

Nitro Bloc Year Measure
a        
x        
1         3.8
a       
 x        
2         3.9
a         x         3         2.0
a         y         1         3.7
a         y         2        
2.4
a         y         3        
1.2
b         x       
 1         4.0
b         x        
2         2.5
and so on...
 

So, I am trying this code, because I want to test each factor and the
interaction...
lme=lme(measure ~ bloc + nitro + bloc*nitro, random= ~ 1|year,
data=lme)
summary(lme)
The results that I am obtaining are not correct, because
I calculated the degrees of fredom and they are not
correct... According to this design I will get two errors one for the
whole plot and other for the subplot....
 
Well, as I told you, I am still learning... Any suggestions...
 
Thanks in advance,
 
Ribeiro
