Dear all,
I am quite new to R and I am having trouble writing the polynomial
contrasts for an ordinal factor in MANOVA.
# I have a model such as this
fit<-manova(cbind(Y1,Y2,Y3)~Groups,data=Events) # where groups is an
ordinal factor with 4 levels
# how to set polynomial contrasts for the "Groups" factor ?

Thank you very much in advance for any help!

Best regards,
Mauro
