[R] anova help

[Joe King]

Ok well heres my data, with the second variable (B variable) being the
random variable and the other fixed. Although the F values are about half of
what SPSS puts out.

 

My code is anova(lm(dependentrandom~typemusic+typemusic*musicselection))

 

This is just dummy data for a class but I am trying to use the data I am
running in SPSS to learn R. I am also in an R class but we are not going to
learn ANOVA.

Hi Joe,

you might want to have a look at the nlme package with the lme command.

Another option is the more advanced lmer package.

 

Lastly, you could have a look at the ?aov command, and notice the option of
using the +Error() term (but that would only work for balanced design cases,
so I've heard, so be aware)

Hi all, I am trying to run a two factor anova, but one of the factors is a
random factor, now I am also running in SPSS and it seems its dividing by
the wrong term to get the appropriate F term. here is my data. In SPSS the F
scores about double the ones in R, how can I specify one of my factors as a
random factor or change it to where it does the right model fitting? I am
using the lm command instead of glm. I am new to R so this might seem basic.
