00:35:25 Russ Hyde: For zooming into a ggplot in shiny: https://shiny.rstudio.com/gallery/plot-interaction-zoom.html
00:41:16 Layla Bouzoubaa: It works better in my opinion than basic ggplot
00:41:20 Layla Bouzoubaa: Since its interactive

00:37:21 Ryan Metcalf: As you can see, dataset uses the req function, and the outputs don't do any checking. Unlike using return(NULL), when you use req to check your preconditions, a failure not only stops the current calculation (the dataset reactive expression, in this case) but also any callers on the call stack. In this case, if the user has not chosen a dataset, then output$plot and output$table both stop upon calling dataset().

00:25:00 Christopher Maronga: Can I use this technique{re() and validate} to limit the ranges of my user inputs, for instance numericInput() between allowable ranges?
00:28:59 Ryan Metcalf: @Chris, for example: https://shiny.rstudio.com/tutorial/written-tutorial/lesson3/
00:29:29 Christopher Maronga: thank you
00:31:04 Ryan Metcalf: The example at the bottom (after you expand) shows a sliderInput with a min, max, and a initial entry. We can rap this into req() and force the system to receive a valid input otherwise provide a ShinyFeedback(). This can also work with a textual input or even with some from of upload. In essence, we can wrap the majority of our user input functions into this validation / feedback process.
