title: Unable to convert JSON to dataframe
body: <p>I want to convert a json-file into a dataframe in R. With the following code:</p>
  
  <pre><code>link &lt;- 'https://www.dropbox.com/s/ckfn1fpkcix1ccu/bevingenbag.json'
  document &lt;- fromJSON(file = link, method = 'C')
  bev &lt;- do.call("cbind", document)
  </code></pre>
  
  <p>i'm getting this:</p>
  
  <pre><code>    type                features
  1   FeatureCollection   list(type = "Feature", geometry = list(type = "Point", coordinates = c(6.54800000288927, 52.9920000044505)), properties = list(gid = "1496600", yymmdd = "19861226", lat = "52.992", lon = "6.548", mag = "2.8", depth = "1.0", knmilocatie = "Assen", baglocatie = "Assen", tijd = "74751"))
  </code></pre>
  
  <p>which is the first row of a matrix. All the other rows have the same structure. I'm interested in the <code>properties = list(gid = "1496600", yymmdd = "19861226", lat = "52.992", lon = "6.548", mag = "2.8", depth = "1.0", knmilocatie = "Assen", baglocatie = "Assen", tijd = "74751")</code> part, which should be converted into a dataframe with the columns <code>gid, yymmdd, lat, lon, mag, depth, knmilocatie, baglocatie, tijd</code>.</p>
  
  <p>I searched for and tryed several solutions but none of them worked. I used the rjson package for this. I also tryed the RJSONIO &amp; jsonlite package, but was unable to extract the desired information.</p>
  
  <p>Anyone an idea how to solve this problem?</p>
