Question

在上一个问题中，我询问是否使用R中的twitteR软件包从Haaretz Twitter Feed（@haaretzcom）下载大量Twitter粉丝（及其位置，创建日期，关注者数量等）（请参阅Work around rate limit for extracting large list of user information using twitteR package in R）。 Twitter提要有超过90,000个关注者，我可以使用下面的代码下载完整的关注者列表没问题。

   require(twitteR)
   require(ROAuth)
   #Loading the Twitter OAuthorization
   load("~/Dropbox/Twitter/my_oauth")

   #Confirming the OAuth
   registerTwitterOAuth(my_oauth)

  # opening list to download
  haaretz_followers<-getUser("haaretzcom")$getFollowerIDs(retryOnRateLimit=9999999)

  for (follower in haaretz_followers){
   Sys.sleep(5)
   haaretz_followers_info<-lookupUsers(haaretz_followers)

   haaretz_followers_full<-twListToDF(haaretz_followers_info)

   #Export data to csv
  write.table(haaretz_followers_full, file = "haaretz_twitter_followers.csv",  sep=",")
 }

该代码可用于提取许多用户。但是，每当我遇到某个用户时，我都会收到以下错误：

Error in twFromJSON(out) :
RMate stopped at line 51
Error: Malformed response from server, was not JSON.
RMate stopped at line 51
The most likely cause of this error is Twitter returning a character which
can't be properly parsed by R. Generally the only remedy is to wait long
enough for the offending character to disappear from searches (e.g. if
using searchTwitter()).
Calls: twListToDF ... lookupUsers -> lapply -> FUN -> <Anonymous> -> twFromJSON
Execution halted

即使我在twitteR包之后加载了RJSONIO包，我也遇到了这个问题。通过一些研究，似乎twitteR和RJSONIO包在解析非UTF-8或ASCII字符（阿拉伯语等）http://lists.hexdump.org/pipermail/twitter-users-hexdump.org/2013-May/000335.html时遇到问题。有没有办法在我的代码中简单地忽略非UTF-8或ASCII，并仍然提取所有关注者信息？任何帮助将不胜感激。

有一个包更新（1.1.7），解决了这个问题。见：https://github.com/geoffjentry/twitteR/blob/master/NEWS
