 When you work with large data sets, modifying and retrieving values creates a logistical problem of its own. How can you search through the data to find the values that you want to modify or retrieve? As an R user, you can do this with logical subsetting. Create a logical test with logical and Boolean operators and then use the test as an index in R's bracket notation. R will return the values that you are looking for, even if you do not know where they are.
 
-Retrieving individual values will not be your only concern as an R programmer. You'll also need to retrieve entire data sets themselves; for example, you may call one in a function. [Environments] will teach you how R looks up and saves data sets and other R objects in its environment system. You'll then use this knowledge to fix the `deal` and `shuffle` functions.
