The generic stats::median method is defined as median <- function (x, na.rm = FALSE) {UseMethod("median")}
I suggest that this should become median <- function (x, na.rm = FALSE, ...) {UseMethod("median")} This would allow additional S3 methods to be developed with additional arguments. Currently I have to over-ride this generic definition in the demography package because median.demogdata has several other arguments. This shouldn't break any code, and will make it easier for new S3 methods to be developed. It is also consistent with almost all other S3 methods which do include an ellipsis. ------------------------------------------------------------- Rob J Hyndman Professor of Statistics, Monash University www.robjhyndman.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
