The median() function assigns a name, "NA", to its return value if the return value is NA and the input vector has names, otherwise the names attribute is NULL. This looks strange and inconsistent with the behavior of mean().
This inconsistency becomes a problem when median() is used inside user code that relies on consistent naming convention.
> foo <- c(x=as.numeric(NA), y=as.numeric(NA), z=as.numeric(NA))
## no names in input
> foo <- rep(as.numeric(NA), 3)
