R:如何将列表保存到 csv 中？

Question

所以我实际上在 twitteR 上工作，我需要一种方法将我的推文存储到 csv 文件中，并在需要时将其拉出。这是因为我想编译我收集的推文，然后将它们应用于我的算法以稍后进行计算。
所以，我想试试

            write.csv(tweets, file = "newfile", row.names = TRUE, sep = ',', col.names = TRUE)

仅在创建数据框 tho :/时才有效。
我收集的推文看起来像这样

 [[1]]
 [1] "anonymous: boring!"

 [[2]]
 [1] "anonymous: random message !"

....
......

有任何想法吗？

编辑:我的 str(tweets) 这只是我刚刚删除的 3 条推文

Answer 1

未经测试，但从我在网上阅读的内容来看，以下内容似乎应该有效:

转换 list到 data.frame

library(plyr) 
tweets.df = ldply(tweets, function(t) t$toDataFrame())

使用 write.csv和以前一样，但只是在 tweets.df 上对象而不是 tweets目的。

write.csv(tweets.df, file = "newfile.csv")
