从字符串向量中删除方括号 [英] Remove square brackets from a string vector

问题描述

我有一个字符向量，其中每个元素都用括号括起来.我想删除括号，只需要字符串.

I have a character vector in which each element is enclosed in brackets. I want to remove the brackets and just have the string.

所以我尝试了:

n = c("[Dave]", "[Tony]", "[Sara]")

paste("", n, "", sep="")

不幸的是，由于某种原因，这不起作用.

Unfortunately, this doesn't work for some reason.

在使用相同的代码之前，我已经执行了相同的任务，但不确定为什么这次不起作用.

I've performed the same task before using this same code, and am not sure why it's not working this time.

我想从 '[Dave]' 转到 'Dave'.

我做错了什么?

推荐答案

你可以像这样删除括号:

You could gsub out the brackets like so:

n = c("[Dave]", "[Tony]", "[Sara]")

gsub("\\[|\\]", "", n)
[1] "Dave" "Tony" "Sara"
