Compute the sample median.
median(x, na.rm = FALSE)
- an object for which a method has been defined, or a numeric vector containing the values whose median is to be computed.
- a logical value indicating whether
NAvalues should be stripped before the computation proceeds.
This is a generic function for which methods can be written. However, the default method makes use of
mean from package base both 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.
The default method returns a length-one object of the same type as
x, except when
x is 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
