I have a rather basic question. How can I get R to generate a ANOVA table
and a f-value for a hypothesis test such as:
Data: group1 values: 5.2 4.5 6.0 6.1 6.7 5.8
group2 values: 6.5 8.0 6.1 7.5 5.9 5.6
...
H0: mean1 = mean2 = mean3 = mean4
HA: at least two means different
where I want to evaluate using a f test statistic?
F = MSTr/MSE
I'd like a table similar to one that Minitab would produce:
Df Sum Sq Mean Sq F value
mean1
mean2
mean3
Error
Secondly, how can do a second evaluation using a multiple ANOVA compare using
Tukey's procedure?
Thanks
BK
