title: Retweet count for specific tweet
body: <p>I'm using "TwitteR" package and R program to retrieve tweets information. Even though Twitter API provides</p>
  
  <pre><code>retweet_count’ function(https://dev.twitter.com/docs/faq#6899)
  </code></pre>
  
  <p>I couldn't figure out how to utilize it within R. ( Maybe using '<code>getURL</code>' function in 'RCurl' package?)</p>
  
  <p>Basically, I'm looking for ways to</p>
  
  <ol>
  <li><p>the number of times specific tweet has been retweeted </p></li>
  <li><p>Using Streaming API in R for getting real time information such as</p>
  
  <p>a. new followers join those users, and </p>
  
  <p>b. when they post tweets or retweets, and </p>
  
  <p>c. when the tweets they have posted are re-tweeted by someone else</p></li>
  </ol>
  
  <p>I would appreciate if anyone could help me out finding leads to get any of these information.</p>
