title: r programming --- twitteR OAuthFactory object error
body: <p>I am setting up an R session to be able to download twitter feeds. I got stumbled on the very step with R citing 'object OAuthFactory not found'. I have all the libraries needed for the program and packages installed: Here is my code</p>
  
  <pre><code>my.key &lt;- "xxx"
  
  #consumer secret
  my.secret &lt;- "xxx"
  
  cred &lt;- OAuthFactory$new(consumerKey=my.key, consumerSecret=my.secret,
      requestURL = 'https://api.twitter.com/oauth/request_token',
      accessURL = 'https://api.twitter.com/oauth/access_token',
      authURL   = 'https://api.twitter.com/oauth/authorize')
  
  Error: object 'OAuthFactory' not found
  </code></pre>
  
  <p>Thanks for your help in advance!</p>
