Duplicate and concatenate in R, we will explore how to use the `str_dup`

function in R to duplicate and concatenate strings within a character vector.

The `str_dup`

function is part of the `stringr`

package, which provides a variety of functions for working with strings.

**Example Data**

To demonstrate the usage of `str_dup`

, we will create a character string `x`

containing the letters “ABC” and three dots:

x <- "ABC..."

**Example: Application of str_dup Function in R**

Before we can use the `str_dup`

function, we need to install and load the `stringr`

package:

install.packages("stringr") library("stringr")

Now, we can use the `str_dup`

function to duplicate the character string `x`

five times:

str_dup(x, 5)

This will output a new character string containing the original string `x`

five times:

# "ABC...ABC...ABC...ABC...ABC..."

As you can see, the `str_dup`

function duplicates the original string `x`

five times and concatenates the results into a single character string.

**Conclusion**

In this article, we have learned how to use the `str_dup`

function in R to duplicate and concatenate strings within a character vector.

By using the `str_dup`

function, you can easily create repeated strings for various purposes, such as data manipulation or text analysis.
