## Overview
The **`attr()` function** in R is used to determine or set a specific attribute of an object.

## Syntax
```
attr(x, which, exact = FALSE)

attr(x, which) <- value
``` 

## Parameters

The `attr()` function  takes the following parameter values:
* **`x`**: This represents an object whose attributes are to be accessed.
* **`which`**: This represents a non-empty character string that specifies which attribute is to be accessed.
* **`exact`**: This takes a logical value of whether the `which` value should be matched exactly or not.
* **`value`**: This represents the new value of the attribute.

## Code example






# creating an object
x <- 1:8

# setting a 2 by 4 matrix as an attribute to x
attr(x,"dim") <- c(2, 4)

# printing x
x


## Code explanation


* **Line 2**: We specify that `x` has numeric values starting from `1` and ending at `8`.

* **Line 5**: We define a `2` by `4` matrix as an attribute to `x`, using the `attr()` function.

* **Line 8**: We print the value of `x`.
