我有一个包含这样的句子的小标题：
df <- tibble(sentences = c("Bob is looking for something", "Adriana has an umbrella", "Michael is looking at..."))
另一个包含一长串名字：
names <- tibble(names = c("Bob", "Mary", "Michael", "John", "Etc."))
我想查看句子是否包含列表中的名称，并添加一列来指示是否是这种情况，并获取以下 tibble ：
wanted_df <- tibble(sentences = c("Bob is looking for something", "Adriana has an umbrella", "Michael is looking at..."), check = c(TRUE, FALSE, TRUE))
到目前为止，我已经尝试过，但没有成功：
df <- df %>%
mutate(check = grepl(pattern = names$names, x = df$sentences, fixed = TRUE))
并且 ：
check <- str_detect(names$names %in% df$sentences)
非常感谢您的帮助；）
