Making our dataframe reactive

Using the reactive dataframe

Making dashboard components reactive

Steps to the reactive dataframe pattern

1. Create a sidebar column (using .sidebar).
2. Add user inputs to the sidebar (using xyzInput() Shiny widgets).
3. Make a "dataframe" that reacts to user inputs (using reactive()).
4. Replace the dataframe in the dashboard component code with the reactive version.
5. Wrap each dashboard output with the appropriate Shiny version (renderXyz()).

Let's practice!
