str_length Function in R (Example)

This article illustrates how to return the length of a string with the str_length function in the R programming language.

The article contains these contents:

• Example Data
• Example: Application of str_length Function in R
• Video, Further Resources & Summary

Let’s get started.

Example Data

First, we need to create a character string for the following example:

x <- c("my example string")       # Create character string

In preparation for the example, we also need to install and load the stringr package to R:

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

Example: Application of str_length Function in R

We can use the str_length function as shown below:

str_length(x)                     # Apply str_length function
# 17

The output printed to the RStudio console is 17. In other words: Our string contains of 17 characters.

Note: The str_length function is very similar to the nchar function. You may also have a look at nchar in order to decide which function is better suited for you.

The YouTube video will be added soon.

In addition, you may want to read the related articles on my homepage. I have published numerous articles about the handling of character strings already.
