9. Value names


Perfect! It's time to move on to other topics that will allow us to be more flexible in our coding. Like other programming languages, R allows you to assign names to your values. This allows you to reuse the values in your code instead of having to hard-code the values again.

Such a name is called a variable. If your variable is named weight, you can retrieve its value by simply typing its name, like so:


R will return the value stored by the variable under this name. Note that you don't need quotation marks to retrieve the value of a variable.


We have created a height variable that represents John's height (in centimeters). Retrieve the value of that variable.
