# Here, R will return a token. Open your browser, log into the Twitter account you want to use and go to
# https://api.twitter.com/oauth/authorize?oauth_token=
# Followed by the token. Yes, you have to write the token manually, but you must to this only once per account.
# Twitter will return a six digits PIN, type it into your R console. You're done!
