The default multivariate test would be based on Pillai's
trace. That may meet your needs. Also, note how the following
summary(manova(cbind(v1, v2, v3) ~ g, data = mydata))
summary(aov(cbind(v1, v2, v3) ~ g, data = mydata))
So if I understood your initial request, I think you want
summary(manova()) and not summary(aov()).
hope it helps,
