R Programming error twitteR OAuthFactory object

Question

I'm creating a R session to download twitter feeds.  I have all the libraries needed for the program and packages installed. I got an error which says 'object OAuthFactory not found'.

This is my code:

my.key <- "xxx"

#consumer secret
my.secret <- "xxx"

cred <- OAuthFactory$new(consumerKey=my.key, consumerSecret=my.secret,
    requestURL = 'https://api.twitter.com/oauth/request_token',
    accessURL = 'https://api.twitter.com/oauth/access_token',
    authURL   = 'https://api.twitter.com/oauth/authorize')

Error: object 'OAuthFactory' not found

Answer 1

You need to install the following packages:

install.packages(c('ROAuth','RCurl'))
require('ROAuth')
require('RCurl')
