To write "Hello, World!" in R programming, you can use the print() function to output the text to the console.

Here's the code: 

print("Hello, World!")

When you run this code in R, it will output the text "Hello, World!" to the console.

If you want to save the output to a file, you can use the cat() function to write the text to a file. Here's an example: 

fileConn <- file("output.txt")
cat("Hello, World!", file = fileConn)
close(fileConn)

This code will create a file called "output.txt" and write the text "Hello, World!" to the file. The close() function is used to close the file connection.

That's all there is to it! With just a few lines of code, you can write "Hello, World!" in R programming and output it to the console or save it to a file.
