I have been working with shiny for a little bit and I am trying my hand at generating dynamic UI elements to make data analysis easier for some people in my lab. So far I have had some moderate success in getting the basic functionality to work, but I am struggling with getting the numericRangeInput() function to work with dynamically generated UI the same way that textInput() can like in this example where the isolate() function is used to keep the same values in the input when updating the UI.
