Dear R users, I use the excelent Anova function of the library car because
the easy way to get sphericity correction. Unless I use the scan function. I
have not been able to access the values ââof sum squares and degrees of
freedom for each effect in the univariate summary table.
Example of the car library for Anova function:
library(car)
phase <- factor(rep(c("pretest", "posttest", "followup"), c(5, 5, 5)),
levels=c("pretest", "posttest", "followup"))
hour <- ordered(rep(1:5, 3))
idata <- data.frame(phase, hour)
mod.ok <- lm(cbind(pre.1, pre.2, pre.3, pre.4, pre.5,
post.1, post.2, post.3, post.4, post.5,
fup.1, fup.2, fup.3, fup.4, fup.5) ~
treatment*gender,
data=OBrienKaiser)
av.ok <- Anova(mod.ok, idata=idata, idesign=~phase*hour)
summary(av.ok, multivariate=FALSE)
If you assign the above line to a new object you will get a multivariate
summary and not the univariate one.
my.summary <- summary(av.ok, multivariate=FALSE)
my.summary
Does anyone know how to assign the full univariate output to a new object
or variable. The logical way does not produce the desired result.
Than'ks in advance.
