利用R工具从Twitter中挖掘信息

在使用Twitter API进行握手时， 我遇到了如下错误：

twitCred <- OAuthFactory$new(consumerKey=consumerKey,
+                              
+                              consumerSecret=consumerSecret,
+                              requestURL=requestURL,
+                              accessURL=accessURL,
+                              authURL=authURL)
> 
> twitCred$handshake(cainfo="cacert.pem")
To enable the connection, please direct your web browser to: 
https:/api.twitter.com/oauth/authorize?oauth_token=lio2StTSAjSHH8jie1TgpdtgeLKuS9TS
When complete, record the PIN given to you and provide it here: 2960112

setup_twitter_oauth(consumerKey,consumerSecret,accessToken,accessScret)
[1] "Using direct authentication"
Use a local file to cache OAuth access credentials between R sessions?
1: Yes
2: No

Selection: 1
Adding .httr-oauth to .gitignore
Error in file(con, "w") : cannot open the connection
In addition: Warning message:

谢谢。

尝试使用setwdnew\u目录更改您的R工作目录，看起来您正在尝试在受保护的目录中写入。谢谢您，先生。。。找到了解决方案，现在又收到了推文。。非常非常感谢，先生@美好的
