I'm attempting to mine twitter data in R, and am having trouble getting started. I created a twitter account, an app in twitter developers, changed the settings to read, write, and access, created my access token, and followed instructions to the letter in registering it: My code: > library(twitteR) > download.file(url="http://curl.haxx.se/ca/cacert.pem", + destfile="cacert.pem") > requestURL <- "https://api.twitter.com/oauth/request_token" > accessURL <- "https://api.twitter.com/oauth/access_token" > authURL <- "https://api.twitter.com/oauth/authorize" > consumerKey <-"my key" #took this part out for privacy's sake > consumerSecret <- "my secret" #this too > twitCred <- OAuthFactory$new(consumerKey=consumerKey, consumerSecret = consumerSecret, requestURL = requestURL, accessURL = accessURL, authURL = authURL) > twitCred$handshake(cainfo="cacert.pem") To enable the connection, please direct your web browser to: https://api.twitter.com/oauth/authorize?oauth_token=zxgHXJkYAB3wQ2IVAeyJjeyid7WK6EGPfouGmlx1c When complete, record the PIN given to you and provide it here: 0010819 > registerTwitterOAuth(twitCred) [1] TRUE > save(list="twitCred", file="twitteR_credentials") And yet, this: > s <- searchTwitter('#United', cainfo="cacert.pem") [1] "Unauthorized" Error in twInterfaceObj$doAPICall(cmd, params, "GET", ...) : Error: Unauthorized I'm about to have a temper tantrum. I'd be extremely grateful if someone could explain to me what is going wrong, or, better yet, how to fix it. Thank you.
