Thanks Dieter, Even if I use lm(), I get the following output:
> summary(fit) Df Sum Sq Mean Sq F value Pr(>F) nh1 1 324.0 323.99 139.13 < 2.2e-16 *** nh2 1 723.1 723.12 310.53 < 2.2e-16 *** nh3 1 1794.2 1794.21 770.49 < 2.2e-16 *** Residuals 4604 10721.2 2.33 --- Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ no R squared to be found. The lm() output gives this: > summary(fit) Df Sum Sq Mean Sq F value Pr(>F) nh1 1 324.0 323.99 139.13 < 2.2e-16 *** nh2 1 723.1 723.12 310.53 < 2.2e-16 *** nh3 1 1794.2 1794.21 770.49 < 2.2e-16 *** Residuals 4604 10721.2 2.33 --- Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ I just want to see how wel the model fits... Another strange thing. I did the same calculations in SPSS and got different results, among others, higher p values. lm() and aov() just do linear regressions (anova) right? I tried with the same factorial variables (without interaction effects to test). Thanks!
