从 R 中的字符向量中删除引号 [英] Remove quotes from a character vector in R

问题描述

假设你有一个字符向量:

Suppose you have a character vector:

char <- c("one", "two", "three")

当您引用索引值时，您会得到以下信息:

When you make reference to an index value, you get the following:

> char[1]
[1] "one"

如何从返回值中去掉引号以获得以下内容?

How can you strip off the quote marks from the return value to get the following?

[1] one

推荐答案

as.name(char[1]) 会起作用，虽然我不确定你为什么真的想要这样做 - 引号不会被带入 paste 例如:

as.name(char[1]) will work, although I'm not sure why you'd ever really want to do this -- the quotes won't get carried over in a paste for example:

> paste("I am counting to", char[1], char[2], char[3])
[1] "I am counting to one two three"
