**Not equal to (!=)** is one of the relational operators used for making comparisons. It returns **TRUE** if the first operand is not equal to the second; else returns **FALSE**.

#### Syntax

`!=`

### Example 1: Comparing two objects

```
78 != 35
TRUE != FALSE
TRUE != TRUE
```

#### Output

```
[1] TRUE
[1] TRUE
[1] FALSE
```

### Example 2: Comparing two variables

Suppose you have two variables, **x** and **y**.

```
#creating variables
x<-30
y<-6
#not equal to
x!=y
```

#### Output

`[1] TRUE`

### Example 3: Comparing two vectors

Suppose you have two vectors, v1 and v2.

```
#creating vectors
v1<-c(171, 152)
v2<-c(182, 165)
#not equal to
v1!=v2
```

#### Output

`[1] TRUE TRUE`

In this example, the Not equal to the operator will compare each element of two vectors. It will return a logical value for each of the elements.
