[R] lm with an arbitrary number of terms

[Richard Nixon]

Hello folks,

Any ideas how to do this?

data.frame is a data frame with column names "x1",...,"xn"
y is a response variable of length dim(data.frame)[1]

I want to write a function

function(y, data.frame){
    lm(y~x1+...+xn)
}

This would be easy if n was always the same.
If n is arbitrary how could I feed the x1+...+xn terms into lm(response~terms)?

Thanks
Richard
