Subject: [Rd] Unused argument "na.action" to pairs.formula
Message-ID: <1D69C8DFA9233040B1E6CB0D3475196239A2B2@exnswn1-syd.nexus.csiro.au>

Hi,

I believe that the argument "na.action" is not used in the function
pairs.formula (graphics). I am using R 2.1.1 for Windows, downloaded
from CRAN.

This is the body of the function as it is now:

function (formula, data = NULL, ..., subset, na.action = stats::na.pass)

{
    m <- match.call(expand.dots = FALSE)
    if (is.matrix(eval(m$data, parent.frame()))) 
        m$data <- as.data.frame(data)
    m$... <- NULL
    m$na.action <- stats::na.pass
    m[[1]] <- as.name("model.frame")
    mf <- eval(m, parent.frame())
    pairs(mf, ...)
}

I think the line "m$na.action <- stats::na.pass" should be "m$na.action
<- na.action". Please correct me if I am wrong or this has already been
fixed.

Cheers,
Tim Keighley
