body: <p>This is my query of streamR package, below query is resulting a message as shown - 
  "Capturing tweets...
  Connection to Twitter stream was closed after 600 seconds with up to 74 tweets downloaded."</p>
  
  <p>This is saving a file to my local with name - tweets_keyword.json, but there is no data in it.</p>
  
  <p>library(streamR)</p>
