[R] Trying to learn how to write a function

I am trying to understand how to write an "advanced" function. To do
this, I am examining the code of lm, a small part of the lm code is below. N
> lmfunction (formula, data, subset, weights, na.action, method = "qr", 
    model = TRUE, x = FALSE, y = FALSE, qr = TRUE, singular.ok = TRUE, 
    contrasts = NULL, offset, ...) 
{
    ret.x <- x
    ret.y <- y
    cl <- match.call()
    mf <- match.call(expand.dots = FALSE)
    m <- match(c("formula", "data", "subset",
"weights", "na.action",
        "offset"), names(mf), 0L)
