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
