问题 I have the shiny app below in which the user uploads a file (here I just put the dt in a reactive function) and from there he can choose which columns he wants to display as selectInput() via a pickerInput() . Then he should be able to click on Update2 and see the map. The user should also be able to update the depth and stations values by multiplying all of them with the numericInput() value1 and value2 respectively and create a new sliderInput() and therefore update the dataframe that is

问题 I've created a function which adds a few layers to my Leaflet map on page load. Afterwards, I want it to center the view based up on these layers. let layerGroup = L.featureGroup(); ... // add multiple layers layerGroup.addLayer(L.geoJson(feature)) ... leafletMap.addLayer(layerGroup); leafletMap.fitBounds(layerGroup.getBounds()); It currently works as intended, and the map zooms in in order to fit the bounds. However, when the United States is one of these layers, the map completely zooms out
