In this chapter we've covered a number of rather diverse but related topics. We've described some of the basic "nuts and bolts" tools for entering and transforming network data. The "bigger picture" is to think about network data (and any other, for that matter) as having "structure". Once you begin to see data in this way, you can begin to better imagine the creative possibilities: for example, treating actor-by-attribute data as actor-by-actor, or treating it as attribute-by-attribute. Different research problems may call for quite different ways of looking at, and transforming, the same data structures. We've hardly covered every possibility here, but we have looked at some of the most frequently used tricks.
