In this chapter, you have acquired a solid knowledge of classes, objects, and functions, elements selections in vectors and lists, control structures, and how to read data. These are the fundamentals to start working in R. In the next chapter, useful functions to process and clean data will be covered. These will provide you with useful tools to obtain data from a source, process it in any way desired, and in the end, display it via web applications in Shiny.

In the next chapter, we are going to take a look at different functions and packages for data processing in R.
