Compute the sample median.

`median(x, na.rm = FALSE, …)`

x

an object for which a method has been defined, or a numeric vector containing the values whose median is to be computed.

na.rm

a logical value indicating whether `NA`

values should be stripped before the computation proceeds.

…

potentially further arguments for methods; not used in the default method.

The default method returns a length-one object of the same type as
`x`

, except when `x`

is logical or integer of even length,
when the result will be double.

If there are no values or if `na.rm = FALSE`

and there are `NA`

values the result is `NA`

of the same type as `x`

(or more
generally the result of `x[FALSE][NA]`

).

This is a generic function for which methods can be written. However,
the default method makes use of `is.na`

, `sort`

and
`mean`

from package base all of which are generic, and so
the default method will work for most classes
(e.g., `"Date"`

) for which a median is a reasonable
concept.
