Forbidden error with streaming API

#1

I have a Twitter app. with consumer key,secret as well as Auth. key,
secret set. I had been using this app. with setup_twitter_oauth() all
these days. Then I hit the rate limit issue. So, I wanted to switch to
the Stream API. I use the same consumer key, secret & Auth key,
secret, and then provide the other parameters as below. I get a
’Forbidden’ error :

my_oauth <-
OAuthFactory$new(consumerKey=consumerKey,consumerSecret=consumerSecret,
requestURL=requestURL,accessURL=accessURL, authURL=authURL)
my_oauth$oauthKey="“
my_oauth$oauthSecret=”"
my_oauth$handshakeComplete
[1] FALSE

To enable the connection, please direct your web browser to:

When complete, record the PIN given to you and provide it here:
Error: Forbidden

Can someone help figure out what the problem is? I am not able to figure out those warnings displayed. Also, what is causing the Forbidden? Do I need a special account permission to issue
streaming API? If yes, how to apply for it?
