## You can obtain your own at dev.twitter.com
  library(ROAuth)
  requestURL <- "https://api.twitter.com/oauth/request_token"
  accessURL <- "http://api.twitter.com/oauth/access_token"
  authURL <- "http://api.twitter.com/oauth/authorize"
  consumerKey <- "xxxxxyyyyyzzzzzz"
  consumerSecret <- "xxxxxxyyyyyzzzzzzz111111222222"
  my_oauth <- OAuthFactory$new(consumerKey=consumerKey,
    consumerSecret=consumerSecret, requestURL=requestURL,
    accessURL=accessURL, authURL=authURL)
  my_oauth$handshake(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"))

## capture 10 tweets mentioning the "Rstats" hashtag
  library(streamR)
  filterStream( file.name="tweets_rstats.json",
     track="rstats", tweets=10, oauth=my_oauth )

## exporting those 10 tweets to MongoDB (database name is "tweets" and
