Write Data Frame without Header in R (Example)

In this tutorial, I’ll show how to export a data frame without column names in R.

With that, let’s get started…

Creation of Exemplifying Data

Consider the following example data:

data <- data.frame(x1 = 9:4,    # Create data frame
                   x2 = letters[10:15],
                   x3 = 9)
data                            # Print data frame to RStudio console
#   x1 x2 x3
# 1  9  j  9
# 2  8  k  9
# 3  7  l  9
# 4  6  m  9
# 5  5  n  9
# 6  4  o  9

Have a look at the previous output of the RStudio console. It shows that our example data has six rows and three columns. The variables of our data frame are called x1, x2, and x3.

Example: Exporting CSV File without Header Using write.table Function & col.names Argument

In this example, I’ll illustrate how to write a CSV file without column names.

For this, we have to use the write.table function. Within the write.table function, we have to specify the col.names argument to be equal to FALSE:

write.table(data,               # Write CSV file without header
            "data.csv",
            sep = ";",
            col.names = FALSE)

After running the previous R code, you should find a new CSV file called “data” in your working directory that looks like follows:
