title: How to load the 'stringr' package in R?
body: <p>I am using the "Mining Twitter for Airline Sentiment" tutorial to learn R. (tutorial at <a href="http://www.inside-r.org/howto/mining-twitter-airline-consumer-sentiment" rel="nofollow">http://www.inside-r.org/howto/mining-twitter-airline-consumer-sentiment</a>.)</p>
  
  <p>The parsing algorithm requires loading the external "stringr" library. The R gui terminal consistently says it cannot find the library, even though multiple references exist online.</p>
  
  <p>This is my first experience with an R tutorial. Any suggestions?</p>
  
  <p>Thanks,
