R provides us with some simple ways to create a sequence of numbers, as this is a common need in mathematics. In this article, we will look at three ways to create sequences in R.

The first way we can create sequences is using the `n:m`

expression. This will create a sequence from the number n to m. Let's see an example.

```
1:4
// 1, 2, 3, 4
```

The second way to create a sequence is to use the `seq`

function. The sequences has three paramters you can use: from, to, and by.

```
seq(from = 1, to = 7, by = 2)
# 1, 3, 5, 7
```

The third way, is using the `rep`

function. This function allows you to create sequences that repeat the same number. You will often create sequences of 0's and 1's in mathematics.

```
rep(1, times = 4)
# 1, 1, 1, 1
```
