title: how to remove duplicated tweets in R?
body: <p>I am doing a text mining on tweets
  I have a problem with the duplicate tweets, like this:</p>
  
  <p>"aeCERT: aeCERT provides an ongoing Information Security Awareness Program for Constituents, Law enforcement, Academic sector and Public."</p>
  
  <p>"Salim_aeCERT: aeCERT provides an ongoing Information Security Awareness Program for Constituents, Law enforcement, Academic sector and Public."</p>
  
  <p>I got the same tweets for two different account, how I could eliminate one from my dataset? I have tried this code but the duplicated tweets still appear:</p>
  
  <pre><code>tweets1.df &lt;- do.call("rbind", lapply(tweets, as.data.frame))
  tweets2.df &lt;- tweets1.df[duplicated(tweets1.df ) == FALSE,] 
  dim(tweets2.df)
  </code></pre>
  
  <p>How can I remove duplicate tweets from different accounts?</p>
