我正在使用twitteRR 中的库，想知道是否可以获得与搜索或时间线相关的时间戳。例如，如果使用 searchTwitter 搜索#rstats，我想知道推文是何时发布的……是否需要解析其他参数才能获取该信息？

这是一些示例代码...

library(twitteR)
searchTwitter("#rstats",n=10)

给出以下结果

[[1]]

谷歌后：

 mytweet <- searchTwitter("#chocolate",n=10)
 str(mytweet[[1]])

Reference class 'status' [package "twitteR"] with 10 fields
 $ text        : chr "The #chocolate part of the #croquette. #dumplings #truffles http://t.co/Imwt3tTP"
 $ favorited   : logi FALSE
 $ replyToSN   : chr(0) 
 $ created     : POSIXct[1:1], format: "2013-01-27 16:26:03"
 $ truncated   : logi FALSE
 $ replyToSID  : chr(0) 
 $ id          : chr "295568362526896128"
 $ replyToUID  : chr(0) 
 $ statusSource: chr "&lt;a href=&quot;http://instagr.am&quot;&gt;Instagram&lt;/a&gt;"
 $ screenName  : chr "tahiatmahboob"
 and 33 methods, of which 22 are possibly relevant:
   getCreated, getFavorited, getId, getReplyToSID, getReplyToSN, getReplyToUID, getScreenName, getStatusSource, getText, getTruncated,
   initialize, setCreated, setFavorited, setId, setReplyToSID, setReplyToSN, setReplyToUID, setScreenName, setStatusSource, setText,
   setTruncated, toDataFrame

所以时间戳是：

mytweet[[1]]$created
[1] "2013-01-27 16:26:03 UTC"

twitteR在我阅读您的问题之前从未使用过。无聊的时候可以做一些有趣的事情。

解析结果的一种替代方法（如上面的答案）是使用参数since和until。

例如，您可以这样做：

 res <- searchTwitter("#rstats",n=1000,since='2013-01-24',
                                       until='2013-01-28')

这searchTwitter是 twitter 的 JSON API 的包装器。在此处查看参数的更多详细信息和 JSON 结果的示例。
