 The video in Figure \@ref(fig:plotlyEvents) helps demonstrate how different user events cause different blocks of code to be evaluated on the R server.^[You can also run the example yourself using the following code -- `shiny::runApp(system.file("examples", "plotlyEvents", package = "plotly"))`] Conceptually, you can think of events as different inputs that becomes invalidated when the event is triggered by plotly.js. Moreover, similar to restrictions placed on references to input value(s) in shiny, `event_data()` has to be called _within_ a reactive expressions. As RStudio's [lesson on reactive expressions](http://web.archive.org/web/20160405081516/http://shiny.rstudio.com/tutorial/lesson6/) points out: "A reactive expression is an R expression that uses widget input [(e.g., `event_data()`)] and returns a value."
 
-Any of the `render*()` functions in **shiny** turn a regular R expression into a reactive expression. In Figure \@ref(fig:plotlyEvents), every use of `event_data()` appears within `renderPrint()` since we only need to display the result of the event on the user interface with `verbatimTextOutput()`. In the next section, we use the return result of `event_data()` to display more interesting and informative views of user events.
