Question

我正在使用R中的twitteR软件包来更新我的Twitter状态和分析结果。静态推文功能有效：

library(twitteR)

sess = initSession('username','password')

tweet = tweet('I am a tweet', sess)

但是，当我添加一个变量来显示某些特定结果时，我收到一个错误。

library(twitteR)

sess = initSession('username','password')

res = c(3,5,8)
msg = cat('Results are: ', res, ', that is nice right?')

tweet = tweet(msg, sess)

结果：

Error in twFromJSON(rawToChar(out)) : 
  Error: Client must provide a 'status' parameter with a value.

任何建议都表示赞赏。

Answer 1

这是我运行代码时得到的结果：

> res = c(3,5,8)
> msg = cat('Results are: ', res, ', that is nice right?')
Results are:  3 5 8 , that is nice right?> 
> msg
NULL

问题是cat将字符串打印到stdout，而不是将它们作为字符串返回。你想要的是：

> res = c(3,5,8)
> msg = paste('Results are: ', toString(res), ', that is nice right?', sep='')
> msg
[1] "Results are: 3, 5, 8, that is nice right?"

如何在R twitteR更新中插入变量？
