R：在字符串中添加单引号 [英] R: Add single quote to string

问题描述

我尝试在字符串中添加单引号，但看不到该怎么做。例如，我想用'ABC'代替ABC。

I try to add single quotes to a string but don't see how to do it. For instance I would like to replace ABC by 'ABC'.

我玩过粘贴，猫，印刷品，但不知道怎么做。

I have played with paste, cat, print but don't see how to do it.

有什么解决方案吗？

谢谢，
Vincent

Thanks, Vincent

推荐答案

只需使用粘贴：

R> paste("'", "ABC", "'", sep="")
[1] "'ABC'"

或新品种

R> paste0("'", "ABC", "'")
[1] "'ABC'"
