title: specific country map with district/cities using R
body: <p>I am trying to draw some specific countries map such as, <strong>Bangladesh, Bhutan</strong> etc. with its district/cities in R. As an example, I can draw US map using the following lines of codes. Is there any such <code>library/package</code> that can give me any countries map with its cities/district/province? Any clue is appreciated. </p>
  
  <pre><code>library(maps)
  states &lt;- map_data("state")
  </code></pre>
