[R] Function input for regression analysis

[flokke]

Dear all,
I have a small question.
I would like to write a function for a regression analysis that an be
applied to every dataset.
Now my problem is that I do not know what I have to implement then as input
for the function

mytest <- function (x,y) {
                                    beta <- solve(t(x)%*%x%*%t(x)%*%y

                                    (....)
                                   }

would not make any sense, because then you could only use a dataset with y
and one predictor,
but I just dont know how to do this in another way.

Has someone any idea?

Thanks a lot!
Cheers, Maria
