Hi,
I would suggest you to check the structure of your summary object with
str(), like this:
S <- summary(M, test="Pillai")
str(S)
You will then see how to access each element of it.
If you cannot manage to do it yourself, then provide an example, or at
least the output from str(s).
By the way, when you get an error, then copy it so that we have a better
idea of what happens.
HTH,
Ivan

I just finished a MANOVA test and got the following output:
summary(M, test="Pillai")
Df Pillai approx F num Df den Df Pr(>F)
as.factor(X) 3 1.1922 6.5948 36 360< 2.2e-16 ***
Residuals 129
---
Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1
I would like to store the values Df=3, Pillai=1.1922, P-value, etc. as a
vector.
I have tried the following code that did not work:
S=summary(M, test="Pillai")
S1<-as.vector(S$Df, S$Pillai)
but I am getting an error every time. I have also tried just S$Df. Is there
a way to find out if "Df" and "Pillai" are correct headers to reference. For
example maybe it is "df" or "degreesfreedom" etc.
I know the concept works because I have used it for logistic regression.
>v1<- as.vector(exp(L1$coefficients))
The difference is that I know "coefficients" is the correct header to refer
to.
