将标点符号转换为空格

Question

我有一堆带有标点符号的字符串，我想将其转换为空格：

"This is a string. In addition, this is a string (with one more)."

会变成：

"This is a string  In addition  this is a string  with one more  "

我可以通过stringr包（str_replace_all()）一次一个标点符号手动执行此操作（，/。/！/（/）/等），但是我好奇，如果有一种更快的方式我会假设使用正则表达式。

有什么建议吗？

Answer 1

x <- "This is a string. In addition, this is a string (with one more)."
gsub("[[:punct:]]", " ", x)
[1] "This is a string  In addition  this is a string  with one more  "

有关?gsub类的详细信息，请参阅?regex进行快速替换，[[:punct:]]，

‘[:punct:]’ Punctuation characters:
      ‘! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { |
      } ~’.

Answer 2

查看?regex

library(stringr)
str_replace_all(x, '[[:punct:]]',' ')

"This is a string  In addition  this is a string  with one more  "
