r代码删除包含@的单词 [英] r code removing words containing @

问题描述

我想将包含符号@的所有单词替换为特定单词.我使用了gsub，因此将其应用于字符向量.不断出现的问题是当我使用时:

I want to replace all words containing the symbol @ with a specific word. I am used gsub and therefore am applying it to a character vector. The issue that keeps occuring is that when I use:

gsub(".*@.*", "email", data) 

该字符向量的该部分中的所有文本都将被删除.

all of the text in that portion of the character vector gets deleted.

有许多不同长度的电子邮件，因此我无法将字符前面和后面的字符设置为特定的数字.

There are multiple different emails all with different lengths so I can't set the characters prior and characters after to a specific number.

有什么建议吗?

我已经完成了很多有关正则表达式的阅读，但是我尝试的所有尝试都失败了.

I've done my fair share of reading about regex but everything I tried failed.

这是一个例子:

data <- c("This is an example. Here is my email: [e-mail]. Thank you")

data <- gsub(".*@.*", "email", data)

它返回 [1]电子邮件"

it returns [1] "email"

当我想要的时候 [1]这是一个例子.这是我的电子邮件:电子邮件.谢谢"

when I want [1] "This is an example. Here is my email: email. Thank you"

推荐答案

您可以使用以下内容.

gsub('\\S+@\\S+', 'email', data)

说明:

\S与任何非空白字符匹配.因此，这里我们匹配任何非空白字符(1或更多)，后跟@，然后是任何非空白字符(1或更多)次)

\S matches any non-whitespace character. So here we match for any non-whitespace character (1 or more times) preceded by @ followed by any non-whitespace character (1 or more times)
