To write to an existing file, you must add a parameter to the open function: 'a' - Append - will append to the end of the file 'w' - Write - will overwrite any existing content. If your subdomain is, write 'sub' for the Host. TXT: Your unique security token provided in the Admin console's verification instructions. The token is a 68-character string that begins with google-site-verification=, followed by 43 additional characters.

Previously, we described R base functions (read.delim() and read.csv()) for importing txt and csv files into R.

In this article, you’ll learn how to export or write data from R to .txt (tab-separated values) and .csv (comma-separated values) file formats.

Launch RStudio as described here: Running RStudio and setting up your working directory


The R base function write.table() can be used to export a data frame or a matrix to a file.

A simplified format is as follow:

  • x: a matrix or a data frame to be written.
  • file: a character specifying the name of the result file.
  • sep: the field separator string, e.g., sep = “t” (for tab-separated value).
  • dec: the string to be used as decimal separator. Default is “.”
  • row.names: either a logical value indicating whether the row names of x are to be written along with x, or a character vector of row names to be written.
  • col.names: either a logical value indicating whether the column names of x are to be written along with x, or a character vector of column names to be written. If col.names = NA and row.names = TRUE a blank column name is added, which is the convention used for CSV files to be read by spreadsheets.

It’s also possible to write csv files using the functions write.csv() and write.csv2().

  • write.csv() uses “.” for the decimal point and a comma (“,”) for the separator.
  • write.csv2() uses a comma (“,”) for the decimal point and a semicolon (“;”) for the separator.

The syntax is as follow:

The R code below exports the built-in Rmtcars data set to a tab-separated ( sep = “t”) file called mtcars.txt in the current working directory:

If you don’t want to write row names, use row.names = FALSE as follow:

  • Write data from R to a txt file: write.table(my_data, file = “my_data.txt”, sep = “”)

  • Write data from R to a csv file: write.csv(my_data, file = “my_data.csv”)

This analysis has been performed using R (ver. 3.2.3).

Python file method write() writes a string str to the file. There is no return value. Due to buffering, the string may not actually show up in the file until the flush() or close() method is called.
