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.
