Not like I should be messing with this at this point, but I wanted to retrieve a tweet to provide evidence for a point. Anyway, instead of the like 50 step process in the past, you now follow the instructions in the TwitterR readme: http://cran.r-project.org/web/packages/twitteR/README.html with the exception of you now put your access token and secret in the *single command* now, too, like so:
setup_twitter_oauth(consumer_key, consumer_secret, access_token=NULL, access_secret=NULL)
Then you can just search or whatever. Wow!
Very nice. How much time did I spend playing with the old method?
