A vector is a collection of elements, a basic data structure. Vectors are crucial in RStudio because they can used to represent variables. The data types contained by a vector could be logical e.g (`TRUE, FALSE`

), integer e.g (`1, 2, 3`

), or character e.g (`"Roula", "Micheal"`

).

The `c()`

function is very useful as it allows us to create a vector in R. The c stands for **c**ombine (or concatenate), because multiple elements are combined into a vector.

```
x <-c(1,2,3,4,5,6,7,8,9,10)
```

```
x
```

An important property of vectors is their length. The length of a vector is the count of how many elements are within it.

```
length(x)
```

Additionally, you may create a vector using the `seq()`

function. The seq() function generates a sequence of numbers. For example, if you want to generate a sequence of numbers from 0 to 30 incremented by 3 you can do so using the following command

```
seq(from=0, to=30, by=3)
```
