The length of a string means the total number of characters present in a given string.

For example, the string `"Programiz"`

has the length **9**.

In R, there are two ways to find the length of a string. We can use the `nchar()`

function

or the `str_length()`

function from the `stringr`

package.

## Example 1: Length of a String in R Using nchar()

```
# create a string
string1 <- "Programiz"
# use nchar() to find length of string1
result <- nchar(string1)
cat("Total Length:", result)
```

**Output**

Total Length: 9

In the above example, we have used the `nchar()`

function to find the length of a string variable named `string1`.

Since `string1` contains a string `"Programiz"`

, which has a total of **9** characters. So `nchar()`

returns **9**.

## Example 2: Length of a String in R Using str_length()

In order to use the `str_length()`

function, we first import the `stringr`

package.

```
# import stringr package
library(stringr)
string1 <- "Programiz"
# use str_length() of stringr package to find length
result <- str_length(string1)
cat("Total length:", result)
```

**Output**

Total length: 9

Here, we have used the `str_length()`

function provided by the `stringr`

package to find the length of `string1`.
