str_dup Function in R (stringr Package)
In this R tutorial you’ll learn how to use the str_dup function to duplicate and concatenate strings within a character vector.
The tutorial will contain this content:
- Creation of Example Data
- Example: Application of str_dup Function in R
- Video, Further Resources & Summary
So now the part you have been waiting for – the examples:
Creation of Example Data
First, we need to create a character string, which we can use in the example of this R tutorial. Consider the following character string in R:
x <- "ABC..." # Create example character string
Our example string contains the letters ABC and three dots. Now let’s apply the str_dup function to this character string…
Example: Application of str_dup Function in R
Before we can access the functions of the stringr package, we need to install and load the package:
install.packages("stringr") # Install stringr package library("stringr") # Load stringr package
Now, we can use the str_dup function as shown below:
str_dup(x, 5) # Apply str_dup function # "ABC...ABC...ABC...ABC...ABC..."
In the previous R code we specified that we want to duplicate the character string stored in the data object x five times.
Based on the RStudio console output of the previous R code, you can see the result: The str_dup command returned a new character string containing our example string five times in a single concatenated character string.

Do you want to know more about the duplication and concatenation of character strings in R? Then you may have a look at the following video of my YouTube channel. I’m explaining the R programming code of this post in the video:
The YouTube video will be added soon.
Furthermore, you may have a look at the related tutorials on this homepage. I have released several tutorials already:
Summary: In this tutorial you learned how to apply the str_dup function in order to duplicate and concatenate strings within a character vector in the R programming language. In case you have additional questions and/or comments, don’t hesitate to tell me about it in the comments section.
