In this tutorial you’ll learn how to exchange special characters with accents in the R programming language.

Let’s dive into it:


Creating Example Data

We’ll use the following data as basement for this R programming language tutorial:

x <- "áéèàôî"                    # Create character string
x                                # Print character string
# "áéèàôî"

The previous output of the RStudio console shows the structure of our example data: It’s a character string containing several letters with accents.


Example: Translate Special Characters Using chartr() Function

The following R syntax illustrates how to use the chartr function to remove accents from special characters in R. Have a look at the following R syntax:

chartr("áéèàôî", "aeeaoi", x)    # Apply chartr
# "aeeaoi"

As you can see, we replaced multiple alphabetical letters with accents in one single line of R code.
