问题 I have an R Shiny where server.R outputs a large number of dynamically generated UI objects. Rather than process hundreds of objects in input to process, I thought I could use bs_accordion() from the bsplus package. I expected bs_accordion() to report the state of the elements it controls back to server.R via the input object. My plan had been to dynamically generate the UI elements for just the currently selected item using renderUI() . Unfortunately as far as I can tell, nothing in the

问题 Friends could help me resolve the following issue: I am inserting three executable codes below, the first generates a map using sftnetworks package, showing the route between two locations. In this case, the two locations to generate the map were defined: from = c(df_spec_clust[1, c("Longitude")], df_spec_clust[1, c("Latitude")]) and to = c (df_spec_prop [4, c ("Longitude")], df_spec_prop [4, c ("Latitude")])] . In the second, I would like to generate the map in Shiny format, but without
