在 R 中使用 strsplit |作为模式[重复]

Question

我需要在字符“|”上拆分一系列字符串例如：

fruits <- c(
  "apples|oranges|pears|bananas",
  "pineapples|mangos|guavas"
)
str_split(fruits, "|")

哪些输出：

[[1]]
 [1] ""  "a" "p" "p" "l" "e" "s" "|" "o" "r" "a" "n" "g" "e" "s" "|"
[17] "p" "e" "a" "r" "s" "|" "b" "a" "n" "a" "n" "a" "s" "" 

[[2]]
 [1] ""  "p" "i" "n" "e" "a" "p" "p" "l" "e" "s" "|" "m" "a" "n" "g"
[17] "o" "s" "|" "g" "u" "a" "v" "a" "s" "" 

这不是我要找的，我想要的

[[1]]
[1] "apples"  "oranges" "pears"   "bananas"

[[2]]
[1] "pineapples" "mangos"     "guavas"  

我认为我在 str_split 的 RegEx 模式参数中输入的内容有问题，但我不确定它有什么问题。

请帮忙，谢谢。

我需要转义“|”

str_split(fruits, "\\|")
