I am trying to use the twitteR package in R and have installed the required packages viz :install.packages("twitteR", "RCurl", "RJSONIO", "stringr") also loaded them as well. But when I try to set the twitter connection using setup_twitter_oauth(api_key, api_secret, token, token_secret) command with required parameters , I get the error : Error: could not find function "setup_twitter_oauth" Don't know what is the problem.Please help.

EDIT:
Following is the result of the sessionInfo() command :

rtwitter
did you call library('twitteR')? – Stedy
Yes, I did call library("twitteR") ,library("plyr") ,library("RCurl") library("RJSONIO") ,library("stringr") and library("httr") – msd
To verify that the packages are loaded and their version numbers, add the output of sessionInfo() to your question. – MrFlick
@MrFlick any suggestions ? – msd
That's odd you get that error. You didn't create a different object with that same name did you? You can try twitteR:::setup_twitter_oauth() to fully specify the package. – MrFlick

install.packages("base64inc") worked for me. Also you can try twitteR:::setup_twitter_oauth(), this also worked for me.
