Comments

Comments start with # and are ignored when R runs the code, letting you leave notes explaining what a piece of code does or why. They don't affect how a script executes, but they make code easier to understand later, whether for someone else or for yourself after time has passed. Good commenting habits pay off especially once scripts grow beyond a few lines.
