# range

##### Range of Values

`range`

returns a vector containing the minimum and maximum of
all the given arguments.

##### Usage

```
range(..., na.rm = FALSE)
"range"(..., na.rm = FALSE, finite = FALSE)
```

##### Arguments

##### Details

`range`

is a generic function: methods can be defined for it
directly or via the `Summary`

group generic.
For this to work properly, the arguments `...`

should be
unnamed, and dispatch is on the first argument.

If `na.rm`

is `FALSE`

, `NA`

and `NaN`

values in any of the arguments will cause `NA`

values
to be returned, otherwise `NA`

values are ignored.

If `finite`

is `TRUE`

, the minimum
and maximum of all finite values is computed, i.e.,
`finite = TRUE`

*includes* `na.rm = TRUE`

.

A special situation occurs when there is no (after omission
of `NA`

s) nonempty argument left, see `min`

.

##### S4 methods

This is part of the S4 `Summary`

group generic. Methods for it must use the signature
`x, ..., na.rm`

.

##### Examples

`library(base)`

```
(r.x <- range(stats::rnorm(100)))
diff(r.x) # the SAMPLE range
x <- c(NA, 1:3, -1:1/0); x
range(x)
range(x, na.rm = TRUE)
range(x, finite = TRUE)
```
