Create Comma Separated Vector in R (Example)


In this R article you’ll learn how to create a vector separated by commas.

Let’s start right away.


Example Data

As a first step, we’ll have to define some data that we can use in the following examples:

x <- c(4, 1, 4, 2, 3, 5)                   # Example vector
x                                          # Print vector
# 4 1 4 2 3 5

Have a look at the previous output of the RStudio console. It shows that the example data is an array containing six numeric values.


Example: Convert Numeric Vector to Comma Separated

The following R programming syntax shows how to use the paste & shQuote functions to change our numeric example vector to a comma separated character vector.

x_cs <- paste(shQuote(x, type = "cmd"),    # Converting vector
              collapse = ", ")
cat(x_cs)                                  # Print updated vector
# "4", "1", "4", "2", "3", "5"

As you can see based on the output of the RStudio console, our new vector is a comma separated vector.
