TwitterMining.R

library(RCurl)
# Set SSL certs globally
options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))

library(twitteR)
reqURL <- "https://api.twitter.com/oauth/request_token"
accessURL <- "https://api.twitter.com/oauth/access_token"
authURL <- "https://api.twitter.com/oauth/authorize"
apiKey <-  "xxxxxxxxxxxxxxxxxxxxxx"
apiSecret <- "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

twitCred <- OAuthFactory$new(
  consumerKey = apiKey, 
  consumerSecret = apiSecret,
  requestURL = reqURL,
  accessURL = accessURL, 
  authURL = authURL
  )

twitCred$handshake(
  cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")
  )

registerTwitterOAuth(twitCred)

There seems to be a new way to do this now, the above ways didn't work for me.

library(ROAuth)

  apiKey <- "#####"
  apiSecret <- "####"
  actoken <- "#####"
  acsecret <- "#####"

setup_twitter_oauth(
  apiKey , 
  apiSecret,
  actoken,
  acsecret
)

After that is done you'll have direct access. More straightforward IMO.

install.packages("twitteR")
install.packages("ROAuth")
library(twitteR)
library(ROAuth)
require(RCurl)

Thanks sickopath, your solution (and mis6036) worked perfectly.

Thanks mis6306, Solution working good !!
