问题描述

我以以下数据为例:

 basketball = c("MISS W. Johnson 18' Pullup Jump Shot",
                "MISS Barnes 12' Pullup Jump Shot",
                "MISS Carter  19' Pullup Jump Shot")

我如何找到最常见的单词或将它们交叉"起来，以便我只得到 "MISS Pullup Jump Shot" 作为结果?

How do I find the most common words or 'intersect' them so that I will only have "MISS Pullup Jump Shot" as the result?

推荐答案

这可行，但鉴于您的问题有点含糊，我不确定它的稳健性.

This works, but I'm not sure how robust it is given your question is a little vague.

Reduce(intersect, strsplit(basketball," "))
#[1] "MISS"   "Pullup" "Jump"   "Shot"
