Summary

In this chapter, we learned about R Shiny's advanced features. Animation, graphics, report development, and using knitr are wonderful professional-level presentation features; using these, anybody can share their results and tell the story about the data in hand. We also discussed and demonstrated the feature of bookmarking the Shiny app's state with different levels of complexity. Interactive plots and tables are new ways to play with data and finding new ways of dynamic presentation. Widgets are like cookbooks and can be used to speed up the app-development process. We can now also code for R users and developers by developing gadgets. Adding a password to our app can give us extra control on restricting the data accessed by end users. In this chapter, we studied most of the latest advanced features of presentation, code sharing, and authentication.
