Creating and exploring environments
Environments are used to store other variables. Mostly, you can think of them as lists, but there's an important extra property that is relevant to writing functions. Every environment has a parent environment (except the empty environment, at the root of the environment tree). This determines which variables R know about at different places in your code.
Facts about the Republic of South Africa are contained in capitals, national_parks, and population.
