Summary
In this chapter, you acquired a general knowledge of useful packages intended to process data. This is particularly useful while creating web applications in Shiny because it will make a difference to traditional web application software; in R, if you can code it, you can display the data in any way you want. To accomplish this, a good background in data processing is essential.
This is the last chapter dedicated to the issues of R that are crucial to building a web application successfully. The next chapters will be dedicated to different Shiny-related tasks. Chapter 4, Shiny Structure – Reactivity Concepts, provides a general explanation of the fundamentals of Shiny, especially the concept of reactivity.
