RStudio 有一个有用的功能:

RStudio has a useful feature:

Session -> Set Working Directory -> To Source File Location

有没有不使用下拉菜单的方法?

也许更好的提问方式是:

maybe a better way of asking is:

有返回当前r脚本文件路径的命令吗?

我也找到了这个帖子，但这些解决方案对我不起作用.甚至不是哈德利的！

I also found this thread, but the solutions didn't work for me. Not even Hadley's!

推荐答案

您可以使用:

并通过您感兴趣的文件的名称更改script.R".

and change "script.R" by the name of the file you're interested in.
