To **generate** **uniformly** **distributed** **random** **numbers** in **R**, you can use the **“runif()”** function. The **runif() **is a built-in **function** that **“generates random numbers from a uniform, continuous probability distribution with a flat shape”**.

The **uniform distribution** in **R** is a continuous probability distribution with a flat shape, while the **normal** **distribution** is a continuous probability distribution with a bell-shaped curve.

**Generate ten uniformly distributed random numbers from 0 to 1 in R**

To **generate** **ten uniformly distributed** **random** **numbers** **from** **0** to** 1** in** R**, use the **runif()** function and pass the three arguments. The first is 10, the second is the min value which is 0, and the third is the max value which is 1.

```
set.seed(123)
random_numbers <- runif(10, min = 0, max = 1)
print(random_numbers)
```

**Output**

```
[1] 0.2875775 0.7883051 0.4089769 0.8830174 0.9404673 0.0455565 0.5281055
[8] 0.8924190 0.5514350 0.4566147
```

In this example, we used the **runif()** function that takes the length of the generating numbers, **10**, and then **min** and **max** values. The **min** and **max** values are the **upper** and **lower** **ranges** in which we need to generate random numbers between.

You can see from the output that it generates ten uniformly distributed random numbers from 0 to 1.

By default, the **runif()** function generates random numbers with a precision of 53 bits, which is the maximum precision supported by R.

To generate random numbers with different precision, use the **runif()** function and **pass** the **bits** **argument**.

**Generating random numbers from a specified range in R**

You can use the **runif() function** to generate random numbers from a uniform distribution over a provided range in R.

Let’s generate 20 uniformly distributed random numbers from 15 to 25 using the **runif()** function.

```
set.seed(123)
random_numbers <- runif(20, min = 15, max = 25)
print(random_numbers)
```

**Output**

```
[1] 17.87578 22.88305 19.08977 23.83017 24.40467 15.45556 20.28105 23.92419
[9] 20.51435 19.56615 24.56833 19.53334 21.77571 20.72633 16.02925 23.99825
[17] 17.46088 15.42060 18.27921 24.54504
```

In this example, we passed the **20** as the first argument, **min = 15** and** max = 25**, because we want 20 random numbers between **15** to **25**.

You can see from the output that it generates 20 random numbers between the **15** to **25** **range**.

**Difference between runif() and rnorm() function**

The **main** **difference** between **runif()** and **rnorm()** is that the **runif()** function generates random numbers from a uniform distribution, while the **rnorm()** **function** generates random numbers from a normal distribution.
