Error in readRDS(pat) : error reading from connection

[valentinap]

Thanks a lot! Now seems working fine!

You'll have to make sure to replace the xxxxxxs with the appropriate keys. If you only made one app, then you'd want to change the code to only include one create_token() call (like code below).

twitter_tokens <- create_token(app = "my_app",
    consumer_key = "asfdaSDfiuSDFoqewirhsf", 
    consumer_secret = "ioasuSYrERKSisdffaoweSDFffdyfp")
# these are not real tokens, they should be replaced with values described in
# obtaining and using access tokens guide.

You could also try installing the github version. There was an unstated dependency, the httpuv package. That shouldn't be the cause here, but it's worth a short. The Github version also has built-in tokens now as well, which will get you going in the short term---in the long term, I wouldn't rely on the built-in tokens as their performance is likely to be inconsistent.

install.packages("devtools")
devtools::install_github("mkearney/rtweet")
library(rtweet)
tw <- search_tweets("rstats")
head(tw)

@valentinap This same problem error comes up if you leave an extra space when copy/pasting the keys or if you forget to enter the callback URL. I'm guessing the latter is more likely. To fix it, go to https://apps.twitter.com, click on your app, and then select "settings." For "callback url" enter the following

http://127.0.0.1:1410

Sorry to bother you again. I had my callback URL as the one you specified before. But even then it is not working . httroauth is not my current working directory. Could you please advice me how to proceed ? The main purpose I wanted to use rtweets is I can use extended keyword which can take more characters. This is actually failing for me

[mkearney]

There are three ways to setup authorization to interact with Twitter's API through rtweet:

1. Save token(s) and setup an environment variable (recommended method).
   • Ideally, you'd setup an environment variable that contains a path to your saved token(s). I made a tokens vignette that describes how to do that, so I'd encourage you to follow that method.
2. Create token(s) object and use token argument.
   • Another method is to create a token and then specify it as the "token" argument in each call. An example of this can be found in the README file.
3. Use token(s) originally created for the twitteR package.
   • For ease of transition, I added some checks to see if an .httr-oauth file was already generated, following the instructions provided by the twitteR package. Depending on system cache options, this can create a problem. Fortunately, until I fix this (which I hope to do relatively soon), the other two methods should still work.

If you've done any/all of that and you're still getting that error, can you share your code so I can get a better idea of what might be going wrong?

[valentinap]

Sorry to reply so in late. I'm following your vignette but when I put my data to create a twitter token I get the following error:

Error in init_oauth1.0(self$endpoint, self$app, permission = self$params$permission, :
Unauthorized (HTTP 401).

This is the code:

twitter_tokens <- c(
create_token(app = "my_app",
consumer_key = "xxxxxxxxxxxxxxx",
consumer_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXX"),
create_token(app = "my_app",
consumer_key = "xxxxxxxxxxxxxxx",
consumer_secret = "XXXXXXXXXXXXXXXXXXXXXXXXXX"))

Thanks in advance for your help

I gave the callback URL as above and also tried to search the tweet. But I am getting the same error

library(rtweet)
library(twitteR)

Attaching package: ‘twitteR’

The following object is masked from ‘package:rtweet’:

lookup_statuses

library(ROAuth)
setup_twitter_oauth("consumer key",

• "consumer secret",
• "access token",,
• "access secret")
  [1] "Using direct authentication"

trump=search_tweets("DonaldTrump",n=10)
Error in readRDS(pat) : error reading from connection

[mkearney]

@mosrihari this is because R is reading the wrong token. for reference: https://github.com/mkearney/rtweet/issues/141

[mosrihari]

Hi mkearney, Even then I am not able to connect to twitter. With reference to #141 , I removed my httr.oauth in my current directory and tried the same. Please note that my current working directory doesnt have .httr.oauth
Please advice on the below code

library(rtweet)
Warning message:
package ‘rtweet’ was built under R version 3.4.3
appname <- "Srihari_NTU"
key <- "consumer key"
secret <- "consumer secret"
twitter_token <- create_token(

• consumer_key = key,
• consumer_secret = secret)
  Error in init_oauth1.0(self$endpoint, self$app, permission = self$params$permission, :
  Unauthorized (HTTP 401).

rstats_tweets <- search_tweets(q = "#rstats",

•                            n = 500)

[mkearney]

Perhaps @mosrihari it's the callback URL that needs to be corrected. Go to https://apps.twitter.com, select your app, and set callback URL to http://127.0.0.1:1410

@mkearney I have the same problem as @mosrihari . My callback URL is correct, I had deleted the .httr-oauth file. I still get

Error in init_oauth1.0(self$endpoint, self$app, permission = self$params$permission,  : 
  Unauthorized (HTTP 401).

I have also tried changing the callback Url to http://127.0.0.1:1410 ,but with zero luck..i am still getting the same error
