确定执行脚本的路径 [英] Determine path of the executing script

问题描述

我有一个名为foo.R的脚本，其中包括位于同一目录中的另一个脚本other.R:

I have a script called foo.R that includes another script other.R, which is in the same directory:

#!/usr/bin/env Rscript
message("Hello")
source("other.R")

但是我希望R能够找到other.R，而不管当前的工作目录是什么.

But I want R to find that other.R no matter what the current working directory.

换句话说，foo.R需要知道它自己的路径.我该怎么办?

In other words, foo.R needs to know its own path. How can I do that?

推荐答案

Here there is a simple solution for the problem. This command:

script.dir <- dirname(sys.frame(1)$ofile)

返回当前脚本文件的路径.保存脚本后，它可以工作.

returns the path of the current script file. It works after the script was saved.
