通过rtweet获得友谊/表演

Question

我试图找到一种使用rtweet包从Twitter中执行对获得友谊/表演的请求的方法，以便分析两个用户之间的关系。但是，我无法让它工作(我确实找到了lookup_friendships()，但它没有做我想做的事情)。用rtweet可以做到这一点吗?如果是的话，怎么做？

Answer 1

这个特性已经添加到rtweet，所以至少应该有一些合理的访问“友谊/显示”API通过lookup_friendships()-and，奖金，它刚刚被接受的版本0.6.0现在在CRAN现在！

所需的输入是source和target (可以是屏幕名或用户ID)。如果只向source或target提供一个用户，那么任何数量的用户--除了Twitter速率限制--都可以在另一个参数中传递。

fds <- lookup_friendships(
  source = "realDonaldTrump",
  target = c("DRUDGE_REPORT", "seanhannity", "HuffPost", "maddow", "cnn")
)
> fds
# A tibble: 60 x 4
   relationship            user       variable           value
          <chr>           <chr>          <chr>           <chr>
 1       source   DRUDGE_REPORT             id        25073877
 2       source   DRUDGE_REPORT         id_str        25073877
 3       source   DRUDGE_REPORT    screen_name realDonaldTrump
 4       source   DRUDGE_REPORT      following            TRUE
 5       source   DRUDGE_REPORT    followed_by           FALSE
 6       source   DRUDGE_REPORT live_following           FALSE
 7       source   DRUDGE_REPORT         can_dm           FALSE
 8       target realDonaldTrump             id        14669951
 9       target realDonaldTrump         id_str        14669951
10       target realDonaldTrump    screen_name   DRUDGE_REPORT
# ... with 50 more rows

还可以在source和target参数中指定多个用户。但是，如果两个参数的长度都大于1，则向量必须具有相同的长度。

## vector of multiple users
usrs <- c(
  "realDonaldTrump", "DRUDGE_REPORT", "seanhannity", "HuffPost", "maddow", "cnn"
)
fds <- lookup_friendships(
  source = usrs, 
  target = usrs
)
> fds
# A tibble: 72 x 4
   relationship            user       variable           value
          <chr>           <chr>          <chr>           <chr>
 1       source realDonaldTrump             id        25073877
 2       source realDonaldTrump         id_str        25073877
 3       source realDonaldTrump    screen_name realDonaldTrump
 4       source realDonaldTrump      following           FALSE
 5       source realDonaldTrump    followed_by           FALSE
 6       source realDonaldTrump live_following           FALSE
 7       source realDonaldTrump         can_dm            TRUE
 8       target realDonaldTrump             id        25073877
 9       target realDonaldTrump         id_str        25073877
10       target realDonaldTrump    screen_name realDonaldTrump
# ... with 62 more rows

还没有多少时间来测试这个。如果遇到问题，请尝试设置parse = FALSE。您需要自己来处理返回的数据，但这可能有助于避免内部解析中的错误。

fds <- lookup_friendships(
      source = usrs, 
      target = usrs,
      parse = FALSE
    )
> str(fds, 3)
List of 6
 $ realDonaldTrump:List of 1
  ..$ relationship:List of 2
  .. ..$ source:List of 16
  .. ..$ target:List of 7
 $ DRUDGE_REPORT  :List of 1
  ..$ relationship:List of 2
  .. ..$ source:List of 16
  .. ..$ target:List of 7

您可能可以使用get_friends()或get_followers()函数。
