twitteR is an R package which provides access to the Twitter API. Most functionality of the API is supported, with a bias towards API calls that are more useful in data analysis as opposed to daily interaction.

• Please read the user vignette, which admittedly can get a bit out of date
• Create a Twitter application at https://dev.twitter.com. Make sure to give the app read, write and direct message authority.
• Take note of the following values from the Twitter app page: "API key", "API secret", "Access token", and "Access token secret".
• You can use the CRAN version (stable) via the standard install.packages("twitteR") or use the github version. To do the latter:
  • install.packages(c("devtools", "rjson", "bit64", "httr"))
  • Make sure to restart your R session at this point
  • library(devtools)
  • install_github("geoffjentry/twitteR")
• At this point you should have twitteR installed and can proceed:
  • library(twitteR)
  • setup_twitter_oauth("API key", "API secret")
    • The API key and API secret are from the Twitter app page above. This will lead you through httr's OAuth authentication process. I recommend you look at the man page for Token in httr for an explanation of how it handles caching.
  • You should be ready to go!
