title: Make leaflet map mobile responsive
body: <p>I have built a leaflet with leaflet package in R. Here a simplified version of the code used</p>
  
  <p>library(leaflet)</p>
  
  <pre><code># dumb data
  Points &lt;- data.frame(lon = c(41.889, 41.882, 41.891), lat = c(12.455, 12.446, 12.459))
  
  # web map
  wland &lt;- 
    leaflet(data = Points) %&gt;% 
    addTiles() %&gt;%
    addCircleMarkers(col = "red", 
                     fillOpacity = 1, 
                     radius = 5,
                     stroke = TRUE,
                     clusterOptions = markerClusterOptions(
                       maxClusterRadius=35, disableClusteringAtZoom=14
                     )) 
  
  saveWidget(wland, "To:/Your/Path/map.html", selfcontained = FALSE)
  </code></pre>
  
  <p>I uploaded the html along with all javascript <a href="http://slow-data.com/webmap/wland.html" rel="nofollow noreferrer">here</a> . It looks fine on desktop, but on mobile it does not respond well: markers remain too small, etc.
  Do you know how to make leaflet mobile responsive? Shall I modify sometihng in the javascript created by R-leaflet?</p>
  
  <p>Thanks,
  Jacopo</p>
