Question

我有两组这样的数据框，我想用它们的字符串

加入它们

> part <- data.frame(name = c("I", "want", "to", "go", "there", "you", "are", "seeing"),
+                    value = c(0.77, 0.55, 0.33, 0.4, 0.5, 0.9, 1.0, 0.91))
> full <- data.frame(sentence = c("I want to go there", "you are seeing"))

如何根据句子中的姓名存在来加入他们？喜欢这个

    name value           sentence
1      I  0.77 I want to go there
2   want  0.55 I want to go there
3     to  0.33 I want to go there
4     go  0.40 I want to go there
5  there  0.50 I want to go there
6    you  0.90     you are seeing
7    are  1.00     you are seeing
8 seeing  0.91     you are seeing

从那里开始工作：

工作但可能效率不高的例子：

sapply(part$name, function(x) {grepl(full[1,1],pattern = x)})

如果字符串包含在其他字符串
