Hi everybody, I'm actually implementing some R functions about "Experimental Designs". I have some problems with the function "terms.formula" which doesn't work like "terms" on S-Plus. I have just seen, in the development part of R, that it exists a new documentation for this function, that include the option "neg.out", but I can't find any new source for it. If someone can help me to solve this problem ... Thank you -- Isabelle Zabalza-Mezghani Tel : 01 47 52 61 99 Institut Fran?ais du P?trole E-mail : isabelle.zabalza-mezghani at ifp.fr 1-4 Av.
