Pet_type is a class variable with two values: "dog" or "cat". Ultimately, I would like to have a graph something like this  my code is  proc glm data = have ; class pet_type ; model logsale = beta gamma alpha pet_type pet_type*beta pet_type*gamma pet_type*alpha/ss3; lsmeans pet_type*gamma/ slice = pet_type; lsmeans pet_type*beta/ slice = pet_type; lsmeans pet_type*alpha/ slice = pet_type; run;   but I've got an error message that "only CLASS variables allowed in this effect." Please help!  ... View more
