hello,

i am fitting a Linear model using R. I have to fit the model considering all
the interaction effects of order 1 of the independent variables. But I have
9 variables. So, it will be difficult for me to write all the 36
combinations in the model. Can anyone please help how to get this done in
much smarter way??


thanks a lot,
Ashok Varma.
