## Overview
The **`head()` function** in R is used to determine the first or last part of an R object.
## Syntax
```
head(x, n)
```
## Parameter value
The `head()` function takes the following parameter values.
* **`x`**: This represents the R object (a matrix, data.frame, ftable, table, function).
* **`n`**: This represents a single integer. When given a zero or positive value, the output object contains the number of elements for a given vector, the rows for a given matrix or data frame, or lines for a given function. When given a negative value, all but the first or last `n` number of elements of the input R object are returned.
## Return value
The `head()` function returns an object like that of the input object, `x`.
## Example



# creating a data frame object
mydataframe<- data.frame(
   numbers = 1:10,
   alphabets = LETTERS[1:10],
   symbol = c('*', '!', '#', '?', ',', '/', '=', '+', '<', ')')
)

# implementing the head() function returning only 7 rows of the data frame
head(mydataframe, n=7)

## Explanation 
* **Lines 2 to 6**: We create an R object (a data frame) `mydataframe` using the `data.frame()` function.
* **Line 9**: We implement the `head()` function by making the resulting data frame have only `7` rows.

What is the head() function in R?

Determines the start or end of an R object. Takes parameters x and n. Returns a truncated version of x.
