title: R fuse several JSON
body: <p>i'm having struggle to make a JSON from several different JSON in R. I'm making a request to an API while increasing the final parameter in function of the var "individus". For each request i receive a JSON and i only keep the "$top" part of it.</p>
  
  <pre><code>for (i in 1:individus){
      url_req &lt;- paste("api_url", i, sep="")
      list_json1 &lt;- fromJSON(url_req)
  
      if (missing(list_json1) == TRUE){
          inter_json &lt;- list_json1$top
      }else{
          inter_json &lt;- inter_json+list_json1$top
      }
  }
  </code></pre>
  
  <p>My question is how can i fuse those data in a single json a little bit like that :</p>
  
  <pre><code>inter_json &lt;- inter_json+list_json1$top
  </code></pre>
