Thank you very much fabienc. But unfortunately I get the same error:
Error in as.data.frame.default(pippo) :
cannot coerce class "c("manova", "maov", "aov", "mlm", "lm")" to a data.frame
It seems that the function MANOVA is not convertible into a data frame. So how can I extract this information and connect it to the next node?
Thank you
