[Rd] aesthetics of do.call

[Vincent Carey 525-2265]

library(MASS)
G1 = glm(sp~CW, data=crabs, fam=binomial)
G2 = do.call("glm", list(sp~CW, family=binomial, data=crabs))

G1$call is very nice to look at
G2$call is very voluminous

if we revise do.call to

function (what, args, quote = FALSE, envir = parent.frame())
{
    if (!is.list(args))
        stop("second argument must be a list")
    if (quote) {
        enquote <- function(x) as.call(list(as.name("quote"),
            x))
        args <- lapply(args, enquote)
    }
    ans = .Internal(do.call(what, args, envir))
    ans$call = match.call()
    ans
}

G1 and G2 look a lot more alike
