The **minimum** and **maximum** of a dataset are the smallest and the largest entries, respectively. No surprise hereโฆ

The **range** is the difference between the maximum and the minimum, and defines the spread of the data.

Note that a range may be expressed as a single value (the actual difference between maximum and minimum) or by writing `minimum-maximum`

. For instance, in the series (1, 2, 3, 4, 5, 6, 7, 8, 9, 10), the range is 9 or 1-10.

In R, the functions to be used are `min()`

, `max()`

and `range()`

. However, `range()`

returns a vector that contains the minimum and the maximum, respectively. To get the actual difference between these values, you may use `diff(range())`

.

```
my.dataset <- c(1,2,3,4,5,6,7,8,9,10)
min(my.dataset)
```

`## [1] 1`

`max(my.dataset)`

`## [1] 10`

`range(my.dataset)`

`## [1] 1 10`

`diff(range(my.dataset))`

`## [1] 9`
