title: "Regions defined for each Polygons" when mapping shp with R
body: <p>I'm simply trying to visualize some land polygons from natural earth</p>
  
  <pre><code>landData2&lt;-readOGR("/home/pavel/Documents/Studium/Hiwi/Maps/ne_10m_land", "ne_10m_land")
  landGG2&lt;- fortify(landData2) 
  </code></pre>
  
  <p>after the second line I get the message </p>
  
  <p>"Regions defined for each Polygons"</p>
  
  <p>I already fortified it so this post was of no use</p>
  
  <p><a href="https://stackoverflow.com/questions/23913195/why-does-ggplot-give-a-blank-page-with-the-message-regions-defined-for-each-pol">Why does ggplot give a blank page with the message &quot;Regions defined for each Polygons&quot;?</a></p>
  
  <p>I got the data from 
  <a href="http://www.naturalearthdata.com/downloads/10m-physical-vectors/" rel="nofollow noreferrer">http://www.naturalearthdata.com/downloads/10m-physical-vectors/</a>
  I used the simple (not scale ranked) polygons</p>
  
  <p>Does anyone know what it means?</p>
