Part of doing interesting things with data is being able to select just the data that you need for a particular circumstance. You’ve already seen how to get a particular element from a vector or matrix, or a specific component from a list, using indices . A datum’s index is its position in the vector or list. Try it for objects of different length. It's becomes clear that %in% checks whether or not the object is contained in the other object. Whereas == is a logical operator that checks for identity properties. == cheks if elements of a vector is equal to all elements of another vector. In this section you will learn how to sort a list in R. There are three ways for ordering a list in R: sorting the elements in alphabetical order, creating a custom order, or ordering a specific list element.
