问题 I create a map app using shiny and leaflet. It projects a map and some shape files. The shape file has area values. I want to set whether to display the shape file or not based on the area value. Specifically, the sliderInput function is used. Although the display of the shape file is restricted using the sliderInput function, The setview is reset every time the number is changed by sliderInput. Instead of running setview every time, I want you to run setview where you are. What should I do?

问题 I'm writing a shiny app and it was working perfectly fine and all of a sudden I am getting two warning messages. I have gone back to previous copies that ran fine and they are now showing the same error messages, so I am really confused.My code still runs and shows accurate results on the results tab of my shiny dashboard, but I want to track down the warning messages. I debug and the first warning goes away with the rendDataTable and the second warning comes up when I click a tab on my
