Thanks guys. I got same issue resolved by following the instructions on this forum. I simply added all the required library and followed the advice from @ddten to regenerate the all the keys. Now i'm working perfectly.

I had this problem when I went to scrape tweets. I solved it by opening libraries for "httpuv" and "openssl".

Have you both @monitotier @mayankvik2 tried to set the working directory? Like if you make a new folder on desktop named say R Studio then set the working directory as that?
Also regenerate all the keys.
Try writing the code like I did
library("openssl")
library("httpuv")
library("twitteR")
library("tm")
library("stringr")
library("dplyr")

api_key <- " code"
api_secret <- "code"
access_token <- "code"
access_secret <- "code"

setup_twitter_oauth(api_key,api_secret,access_token,access_secret)
origop <- options("httr_oauth_cache")
options(httr_oauth_cache = TRUE)
Also if you have problems with twitteR you can use rtweet.

I get the same error

from twitter.

Same here.

from twitter.

I've tried the following: adding the old version of the httr package, turning my firewall off, adding the base64enc package and nothing worked... And yes, I have installed all the packages AND I used the library function before trying to use them.
I don't know what else to do. I have Windows 8.1 and the most up to date versions of R, R studio, and of the packages.

Here is my code

library("base64enc")
library("twitteR")
library("ROAuth")
library("devtools")
library("memoise")
library("whisker")
library("rstudioapi")
library("git2r")
library("withr")
library("rjson")
library("bit64")
library ("httr")
library ("httpuv")

download.file(url="http://curl.haxx.se/ca/cacert.pem",destfile="cacert.pem")
consumerKey <- "key"
consumerSecret <- "key"
accessToken <- "key"
accessTokenSecret <- "key"

setup_twitter_oauth(consumerKey, consumerSecret, accessToken, accessTokenSecret)

*key= for each line I added the corresponding key from my Twitter App page.

from twitter.

This library resolve my problem.
library("openssl")
library("httpuv")

from twitter.

when i run code OTP get generated but when i use "search" command error can be generated

library(twitteR)

version 3.4.3 please help me

from twitter.

@nadeemkhan786 I get this error when I have poor internet. But you could fix the typos in your code so we're certain that we're on the same page....

from twitter.

@BroVic but i have good internet still i am in same place (error)

I am getting following error. Can anybody guide me?

Can somebody help?

from twitter.

Thanks a lot. Using library openssl and httpuv resolved my Error in check_twitter_oauth() : OAuth authentication error. I was getting worried and in the end of two days I read this post and nailed the error out of my program. Once again thanks!!!

from twitter.

Share your code please @mayankvik2

check working directory

from twitter.

library("twitteR")
library("openssl")
library("httpuv")
library("twitteR")
library("tm")
library("stringr")
library("dplyr")

api_key <- " code"
api_secret <- "code"
access_token <- "code"
access_secret <- "code"

setup_twitter_oauth(api_key,api_secret,access_token,access_secret)
origop <- options("httr_oauth_cache")
options(httr_oauth_cache = TRUE)
I saved my code in desktop and set it as working directory but still the errors of check twitter oauth came.

from twitter.

Tried all the posted solutions but still face the same error:
[1] "Using direct authentication"
Error in check_twitter_oauth() : OAuth authentication error:
This most likely means that you have incorrectly called setup_twitter_oauth()'

Please anyone help to resolve this weird problem. I'm trying for a week to solve this and checked almost all the related forums around the Web. Here is my last place to ask or I will uninstall R and start another language!

from twitter.

from twitter.

I think this is an important issue that has many solutions. Do you think setting a bounty on bountify can be helpful.

I really need to solve this for an important project.

from twitter.

I exactly have the same issue, I have tried everything! it is so frustrating, Let me know if you solve it and how did you do it. I am still working on it too.

from twitter.

@ddten: Thanks for your quick response. After going through more threads I found that this package was missing "base64enc". It helped!
Thanks 😃

from twitter.

from twitter.

I found the solution in a Stackoverflow post. try to run setup_twitter_oauth(consumer_key, consumer_secret) and see what libraries are missing then install them.

from twitter.

Thanks akinsbola452000
I wasn't regenerating the keys!
phew...

from twitter.

during handshake with twitter i get error :-
Error in setup_twitter_oauth(consumer_key = consumerKey, consumer_secret = consumerSecret, :
could not find function "setup_twitter_oauth. please suggest me solution to this issue.
this is my rstudio code and i am using R 3.5.1

setting working directory

library(twitteR)
library(ROAuth)
library(plyr)
library(dplyr)
library(stringr)
library(ggplot2)
library(httr)
library(wordcloud)
library(SentimentAnalysis)
library(sentimentr)
library(RCurl)
library(openssl)
library(httpuv)
library(base64enc)
library(devtools)

oauth_endpoint(authorize = "https://api.twitter.com/oauth",
access = "https://api.twitter.com/oauth/access_token")

#connect to API
download.file(url ='http://curl.haxx.se/ca/cacert.pem', destfile ='cacert.pem')
reqURL <- 'https://api.twitter.com/oauth/request_token'
accessURL <- 'https://api.twitter.com/oauth/access_token'
authURL <- 'https://api.twitter.com/oauth/authorize'

Twitter Application

consumerKey="3GcJah1mIIDPD6c4uIW08L8YU"
consumerSecret="uevNdolvKfdCcG779UpiiD2wHTmP86kAUMqH7I9cjRuA3iJ35r"
accesstoken="869394410-vZb0G5EjJVF9STyLvVDotknPchwhcZ63zftWYyJe"
accesssecret="Ea3kWs4UCTqdNrWA76Wzall5MV2xRorrwlE8DYsc4ul5w"

cred <- OAuthFactory$new(consumerKey=consumerKey,
consumerSecret=consumerSecret,
requestURL=reqURL,
accessURL=accessURL,
authURL=authURL)
cred$handshake(cainfo = system.file('CurlSSL', 'cacert.pem', package = 'RCurl'))

There is URL in console. You need to go to it, get code and enter it on console

Authorization PIN ~DYNAMIC

save(cred, file='twitter authentication.Rdata')

load('twitter authentication.Rdata')

Once you launch the code first time, you can start from this in the future(libraries should be connected)

setup_twitter_oauth(consumer_key = consumerKey,consumer_secret = consumerSecret,
access_token = accesstoken,access_secret = accesssecret)

###*******Step 3: Performs tweets extraction and data cleaning

Harvest some tweets

some_tweets = searchTwitter("statue of unity", n=5000, since = "2017-01-01", lang="en")

some_tweets = searchTwitter("Sardar Vallab Bhai Patel",n=5000, since = "2017-01-01", lang = "en")

(n.some_tweets <- length(some_tweets))

some_tweets.df <- ldply(some_tweets, function(t) t$toDataFrame())
write.csv(some_tweets.df,"tweets.csv")

get the text

some_txt = sapply(some_tweets, function(x) x$getText())

#remove request entities
some_txt = gsub("(RT/via)((?:\b\w*@\w+)+)","", some_txt)
#remove at people
some_txt = gsub("@\w+", "", some_txt)
#remove punctuation
some_txt = gsub("[[:punct:]]", "", some_txt)
#remove numbers
some_txt = gsub("[[:digit:]]","", some_txt)

remove html links

some_txt = gsub("http\w+","", some_txt)

remove unnecessary spaces

some_txt = gsub("[\t]{2,}","", some_txt)
some_txt = gsub("^\s+|\s+$","", some_txt)

define "tolower error handling" function

try.error = function(x)
{
#creating missing values
y = NA
#try catch error
try_error = tryCatch(tolower(x), error=function(e) e)

if not an error

if (!inherits(try_error, "error"))
y = tolower(x)

result

return(y)
}

#Tower case using try.error with sapply
some_txt = sapply(some_txt, try.error)

remove NAS in some_txt

some_txt = some_txt[!is.na(some_txt)]
names(some_txt) = NULL

}

anyone please help me find the issue with my code . i didn't get solution to this problem till yet, so please help me or send me r code to extract tweet that will be working in R 3.5.1.

• i found this problem many time with different code
  Error in setup_twitter_oauth(consumer_key = consumerKey, consumer_secret = consumerSecret, :
