You can subset higher-dimensional structures in three ways: With multiple vectors. If columns specified by number are created, the names (if any) of the corresponding list elements are used to name the columns. Enhanced for loop provides a simpler way to iterate through the elements of a collection or array. Another common use of For loops is when output i depends on output i-1. For example, product(A, B) returns the same as ((x,y) for x in A for y in B). In this example, the data set B contains the variables x3, C1, C2, Z, W, and C4.
