Display Large Numbers Separated with Comma in R (2 Examples)

In this tutorial you’ll learn how to separate numbers with a comma in the R programming language.

The article consists of this content:

It’s time to dive into the examples!

Creation of Example Data

Have a look at the following example data:

x <- 10000000                                     # Example number
x                                                 # Print number to RStudio console
# 1e+07

As you can see based on the previous output of the RStudio console, our example data is a simple data object consisting of one large number.

Example 1: Comma-Separate Numbers with prettyNum Function

This Example shows how to format numeric values to have a comma-separator (i.e. the European way instead of the American way) using the prettyNum command in R.

prettyNum(x, big.mark = ",", scientific = FALSE)  # Apply prettyNum function
# "10,000,000"

Have a look at the previous output of the RStudio console. As you can see, our example number is displayed with a comma-separator

Example 2: Comma-Separate Numbers with format Function

In this Example, I’ll illustrate how to display a large number with commas based on the format function.

format(x, big.mark = ",", scientific = FALSE)     # Apply format function
# "10,000,000"

The output is the same as in Example 1!
