In this chapter, we introduced R shiny, which is an R package used to build interactive apps. We then created a simple Shiny app and later created an app showing how the reactive function works. Later, we created a Shiny app where we used data and, finally, we went through best practices for using the shiny package.

That's all in this chapter, folks. In the next chapter, we'll touch on another useful R package: sparklyr.
