Calling median(c(NA,NA), ns.rm=T) passes a "null" vector to sort. I
would
expect it to return "NA", as suggested below:
> median
function (x, na.rm = FALSE)
{
if (na.rm)
x <- x[!is.na(x)]
else if (any(is.na(x)))
return(NA)
n <- length(x)
if (n == 0) return(NA) ################ suggested fix
half <- (n + 1)/2
if (n%%2 == 1) {
sort(x, partial = half)[half]
}
else {
sum(sort(x, partial = c(half, half + 1))[c(half, half +
1)])/2
}
}
