删除R中的括号 [英] Removing parenthesis in R

问题描述

在这种情况下，我试图从字符串值中删除括号:

I am trying to remove parentheses from a string value in this case this one:

(40.703707008，-73.943257966)

(40.703707008, -73.943257966)

我似乎找不到包含有效代码的帖子；我知道这是一个非常简单的任务，但是我看过以下链接，但是它们要么杀死了我所有的标点符号，要么似乎不起作用.以下是我尝试过的代码.感谢帮助:

I can't seem to find a post with code that works; I know that this is a very simple task, but I've seen the following links but they either kill all my punctuation or don't seem to work. Below is the codes I've tried. Appreciate the help:

从字符串中删除括号

从R中的字符串中删除括号和文本

x = ("(40.703707008, -73.943257966)")
gsub("\\s*\\([^\\)]+\\)","",x)
gsub("\\D", "", x)
gsub("log\\(", "", x)

推荐答案

这些是需要转义的元字符(使用\\)，或者我们可以将其放在方括号中以将其读取为字符.

These are metacharacters that either needs to be escaped (with \\) or we can place it in a square bracket to read it as character.

gsub("[()]", "", x)
#[1] "40.703707008, -73.943257966"
