Summary
In this chapter, we have learned the two main ways to create interactive R Markdown documents. On the one hand, there is the versatile, usable Shiny framework. This includes the inbuilt Shiny documents and presentations options in RStudio, and also the ggvis
package, which takes the advantages of the Shiny framework to build its interactivity. On the other hand, we introduced several already known, and also some new, R packages that make it possible to create several different types of interactive charts. Most of them achieve this by binding R to Existing JavaScript libraries. In the next chapter, you will learn how to write robust R functions.
