Hello World in R Programming

Creating a "Hello, World!" program is a common tradition when introducing a new programming language. In R, it's straightforward:

  1. Using the Console: Simply type the following command in the R console:

    print("Hello, World!")
    
  2. Creating an R script:

    • Open an R script editor (you can use RStudio or any text editor).
    • Write the following line of code:
      print("Hello, World!")
      
    • Save the file with a .R extension, e.g., hello_world.R.
    • Run the script in R or RStudio.

When executed, both methods will display:

[1] "Hello, World!"

This is the basic "Hello, World!" program in R, and it's often the first step to becoming familiar with the language's syntax and environment.
