To save R output to text file, you can use sink() function or cat() function in R.

The following methods show how you can do it with syntax.

Method 1: Use sink() Function

# Rredirecting output to a file
sink("file.txt")

# Save output in file
print("output")

# Close the file
sink()

Method 2: Use cat() Function

cat("output",file = "file.txt")

The following examples show how to save R output in text file using two different methods.

Use sink() Function

Let’s see how we can use sink() function in R:

# Define file name 
sink("sample.txt")

# Send output to text file
print("This is R language output")

# Close connection with file
sink()

Here in the above code we save text data in sample.txt file using sink() function.

Let’s see how we can use cat() function in R:

# Save string to text file
cat("We are learning R language", file = "sample1.txt")

Here in the above code we save text data into sample1.txt file.
