How to select separate sets of markers on the same map using input$map_marker_click?

[grondkat]

Hi,

I'm creating an R shiny leaflet dashboard that contains a set of markers for a set of origin points, and another for destination points. I can add one set of markers, but as soon as I add a second, things get messy. I've tried to use the filter approach described by @jlacko in this post to no avail:

Shiny: Using multiple exclusive reactiveValues for filtering dataset

Hi. I am struggling with reactively filtering dataset based on two mutually exclusive conditions (either or). I created a leafet map, where clicking on polygon/marker returns reactiveValues which can be used for filtering dataset for plotting. If the polygon is clicked, data should be filtered based on region (reactiveValues is a string containing the name of the region). If the marker is clicked, data should be filtered based on single venue (reactiveValues are numerical longitude and latitude values). I want to use same graphs for showing results for either whole region(which of course contains multiple venues) or single venues. Only thing that came to my mind was to somehow erase/inval…

Any suggestions? I don't have a repress, but the post I link to has one.

I am afraid you will need to elaborate a bit on the "things get messy" part.

Are you adding two sets of markets in a single step? or are you updating an existing map based on some user input? What have you tried and what error message seems to be the problem?

If possible include a piece of a reproducible code that illustrates the messy behaviour in your question.
