参见R.utils包的findSourceTraceback()，其中

查找source()在所有调用帧中生成的所有'srcfile'对象。 这使得可以找出当前由source()编写脚本的文件。

我自己刚算出来的。为了确保脚本的可移植性，总是以以下开头:

wd <- setwd(".")
setwd(wd)

It works because "." translates like the Unix command $PWD. Assigning this string to a character object allows you to then insert that character object into setwd() and Presto your code will always run with its current directory as the working directory, no matter whose machine it is on or where in the file structure it is located. (Extra bonus: The wd object can be used with file.path() (ie. file.path(wd, "output_directory") to allow for the creation of a standard output directory regardless of the file path leading to your named directory. This does require you to make the new directory before referencing it this way but that, too, can be aided with the wd object.

或者，下面的代码执行完全相同的事情:

wd <- getwd()
setwd(wd)

或者，如果你不需要对象中的文件路径，你可以简单地:

setwd(".")

你可以在一个bash脚本中包装r脚本，并检索脚本的路径作为bash变量，如下所示:

#!/bin/bash
     # [environment variables can be set here]
     path_to_script=$(dirname $0)

     R --slave<<EOF
        source("$path_to_script/other.R")

     EOF

这对我很有用

library(rstudioapi)    
rstudioapi::getActiveDocumentContext()$path

你可以使用commandArgs函数获取Rscript传递给实际R解释器的所有选项，并搜索——file=。如果你的脚本是从路径启动的，或者它是以一个完整的路径启动的，下面的script.name将以'/'开头。否则，它必须是相对于cwd，你可以连接两个路径，以获得完整的路径。

编辑:听起来你只需要上面的script.name，并剥离路径的最后一个组件。我已经删除了不需要的cwd()样本，并清理了主脚本，并张贴了我的其他. r。只需要保存这个脚本和其他脚本。R脚本放到同一个目录下，chmod +x它们，然后运行主脚本。

主要。接待员:

#!/usr/bin/env Rscript
initial.options <- commandArgs(trailingOnly = FALSE)
file.arg.name <- "--file="
script.name <- sub(file.arg.name, "", initial.options[grep(file.arg.name, initial.options)])
script.basename <- dirname(script.name)
other.name <- file.path(script.basename, "other.R")
print(paste("Sourcing",other.name,"from",script.name))
source(other.name)

其他。接待员:

print("hello")

输出:

burner@firefighter:~$ main.R
[1] "Sourcing /home/burner/bin/other.R from /home/burner/bin/main.R"
[1] "hello"
burner@firefighter:~$ bin/main.R
[1] "Sourcing bin/other.R from bin/main.R"
[1] "hello"
burner@firefighter:~$ cd bin
burner@firefighter:~/bin$ main.R
[1] "Sourcing ./other.R from ./main.R"
[1] "hello"

我相信这就是德曼在找的东西。

#!/usr/bin/env Rscript
print("Hello")

# sad workaround but works :(
programDir <- dirname(sys.frame(1)$ofile)
source(paste(programDir,"other.R",sep='/'))
source(paste(programDir,"other-than-other.R",sep='/'))
