Error in check_twitter_oauth() : OAuth authenticat

I am a newbie on R. I haven practice text mining couple of days. I ben use same OAuth process (actually I am using a few hours ago). Middle of nowhere, I can't pass the authorization process. Because of the problem, I just regenerate all keys and search for answers but I still have same problem. Any help will be much appreciate it.

library(twitteR)
library(httr)
library(tm)
library(NLP)
library(SnowballC)
library(qdap)

> consumer_key <- '**consumer_key**'

> consumer_secret <- '**consumer_secret**'

> access_token <- '**access_token**'

> access_secret <- '**access_secret**'

> setup_twitter_oauth(consumer_key, consumer_secret, access_token, access_secret)

回答1:

I have the following code working fine for me. Make sure you have installed the latest version of package.

options(httr_oauth_cache=T)
api_key <- "api_key here"
api_secret <- "api_secret here"
access_token <- "access_token here"
access_token_secret <- "access_token_secret here "
setup_twitter_oauth(api_key,api_secret,access_token,access_token_secret)

I solved this by installing the base64enc package

I only realized I needed this by running

setup_twitter_oauth(consumer_key, consumer_secret)

This then told me that I was missing base64enc. I installed that and reverted back to the 4 parameter method and it worked

setup_twitter_oauth(consumer_key, consumer_secret, access_token, access_secret)

I had the same issue before, but found a solution online like this:

devtools::install_github("jrowen/twitteR", ref = "oauth_httr_1_0")

It solved the problem. See my answer to a similar problem here https://stackoverflow.com/a/31584935/5147567 for more details
