median
Median
Description
Calculates the median of the input.
The function median is generic.
Usage
median(x, na.rm = FALSE, ...)
## Default S3 method:
median(x, na.rm = FALSE, ...)
Arguments
| x |
a numeric or logical atomic vector.
Missing values (NA) are allowed.
|
| na.rm |
a logical value that specifies if missing values should be removed
before computation.
|
| ... |
extra arguments that are ignored by the core methods for median but may
be used by methods added by packages.
|
Details
If x contains any NAs,
the result will be NA unless na.rm = TRUE.
median is a generic function, only a default method is implemented now.
Value
returns the median of x, where the value has the same type as x.
If the length of x is even the return value is the mean
of the two middle elements.
For even length logical vectors, this mean is 0,
0.5 or 1.
