我对R编程完全不熟悉。 试着靠自己学习。 我有一个场景，我有一堆推文。 我想基于单词来过滤这些推文，如果它在推文文本中退出，那么它应该得到所有的推文以及它的其他属性。

如果推特中存在谷歌词：文本，那么它应该获得该词所包含的所有推文，并且与其他词相同。 我正在尝试自己，但需要一些专家。 最好的方法是什么。请告诉我任何参考资料和书籍或文件。
提前致谢。 Mohan.V

你可以从这样的事情开始：
# words to match
words <- c("google","facebook","twitter")
# sample words. put real jsons here
sample.jsons <- c("google","twitch","twitter","twitch","facebook","twitch","google","facebook","twitter")
# run through all jsons and target words
for(i in seq_along(sample.jsons)){
for(j in seq_along(words)){
# if this condition is TRUE, your criteria is fullfilled
if(words[[j]] %in% sample.jsons[[i]]){
# do whatever you want with the jsons which match your criteria
# right now the following command just outputs all index values at which the criteria is fulfilled
print(i)
}
}
}
但是，我强烈建议您（a）在继续之前先看看SO指南和规则，以及（b）R编程的基础知识。如果你不这样做，你很可能马上遇到下一个问题。
好的开始是：
