This is really a question for r-devel or r-bugs, I think, but not for
the CRAN maintainers.

I would think it is a bug.  Perhaps simply file a bug report?

Again? ;-)

The bug is here:

> range.default
function (..., na.rm = FALSE, finite = FALSE)
{
    x <- c(..., recursive = TRUE)
    if (is.numeric(x)) {
        if (finite)
            x <- x[is.finite(x)]
        else if (na.rm)
            x <- x[!is.na(x)]
    }
    c(min(x), max(x))
}
<environment: namespace:base>

Objects of class Date are not considered numeric, so we end up taking
min and max without removing NA.

One solution could be

if (is.numeric(x) || inherits(x, "Date") ){....}

Re: range( <dates>, na.rm = TRUE ) (PR#10508)

Prof Brian Ripley
In reply to this post by Peter Dalgaard
I don't think that is the right fix.  All methods for min/max should now
support na.rm=TRUE (but not finite=TRUE), so range.default should just
call min and max with that argument.

I'd need to verify those 'should's first ....
