Hi All,

Anyone who can tell me how to make all possible combinations with i.e. a dataset with 3 observations (can be more).

input =

obs var1 var2

obs1 A B obs2 A C obs3 D E

output ( 7 possible combinations) =

obs1 A B -- obs2 A C -- obs3 D E -- obs1 A B obs2 A C -- obs1 A B obs3 D E -- obs2 A C obs3 D E -- obs1 A B obs2 A C obs3 D E

Thanks
