regex - 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，我想将它们转换为空格：

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

会成为：

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

我可以通过stringr包（str_replace_all()）手动执行此操作，一次一个标点符号（，/./！/（/）/等），但我很好奇是否有更快的方法我会假设使用正则表达式.

有什么建议么？

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  "

请参阅?gsub进行这样的快速替换，以及 ?regex有关[[:punct:]]课程的详细信息，即

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

Answer 2

看一下?regex

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

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