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.
