Hi, I am interested in running multivariate contrasts from manova. Here is the code I have currently for a one-way Manova. I would like to run multivariate contrasts for the Year factor. Thanks! #Reduced model t14m1<-manova(as.matrix(t14c[,4:10])~t14c$Year)#get multivariate results summary.manova(t14m1) summary.manova(t14m1,test="Wilks") #Anova in the car package can run Type III tests Anova(t14m1,type="III") Anova(t14m1,type="III",test="Wilks")
In general, if Year is a factor, you may get what you want simply by assigning to
contrasts(t14c$Year) <- See ?contrastsSee also linearHypothesis in the car package and, e.g., demo("bees.contrasts") plus
vignette("HE-examples"),vignette("repeated") in the heplots package
(version heplots_0.9-5 )
