str_flatten Function in R (Example)

In this article you’ll learn how to flatten a string with the str_flatten function in the R programming language.

Let’s start right away.

Creation of Exemplifying Data

Before we can apply the str_flatten function, we need to create a vector of character strings:

x <- c("first string", "abc", "another string")    # Create vector of strings

Furthermore, we need to install and load the stringr package to R:

install.packages("stringr")                        # Install stringr package
library("stringr")                                 # Load stringr package

Now, we can move on to the example!

Example: Application of str_flatten Function in R

We can use the str_flatten function as shown below:

str_flatten(x, collapse = "---")                   # Apply str_flatten function
# "first string---abc---another string"

As you can see based on the output of the RStudio console, the str_flatten function concatenated our character strings by inserting “—” between each string.

You may change the collapse argument to your specific needs.
