title: Add Markers by country name leaflet R
body: <p>I am on Rstudio, and I want to add a marker based on country name. </p>
  
  <p>The variable that contain the number of occurence per country is cnt_country which is in the table below</p>
  
  <pre><code>Morocco                            57381
  France                             35729
  Tunisia                            85563
  Saudi Arabia                       10816
  Turkey                             6725
  </code></pre>
  
  <p>However, when I use leaflet(cnt_country)%>% addTiles()%>% addMarkers() I get an error: cannot infer lat long information.</p>
  
  <p>Is there a way for leaflet to add markers based on country name?</p>
