I have created three separate choropleth maps in Leaflet, all are across Europe with the same countries being used. Each choropleth map shows a different type of ratio and has two layers for 1999 and 2009.
Whilst I have successfully integrated the choropleth maps individually to Shiny with the year layers, I want to be able to just have one Shiny map with a drop down bar to click between the three different choropleth maps, whilst still keeping my layers for each map.
Can anyone suggest how to do this?
