解决方案在2016年出现。非常感谢作者，Sahil Seth!

CRAN和github上的funr包提供了sys.script()函数，该函数获取当前脚本的完整路径。它甚至引用了一个类似的SO帖子。

因此，解是:

myscript。接待员:

#!/usr/bin/env Rscript
f  <-  funr::sys.script()
show(f)

然后执行命令:

user@somewhere:/home$ Rscript myscript.R

将在命令行输出，例如:

"/home/path/to/myscript.R"

到控制台。

I would use a variant of @steamer25 's approach. The point is that I prefer to obtain the last sourced script even when my session was started through Rscript. The following snippet, when included on a file, will provided a variable thisScript containing the normalized path of the script. I confess the (ab)use of source'ing, so sometimes I invoke Rscript and the script provided in the --file argument sources another script that sources another one... Someday I will invest in making my messy code turns into a package.

thisScript <- (function() {
  lastScriptSourced <- tail(unlist(lapply(sys.frames(), function(env) env$ofile)), 1)

  if (is.null(lastScriptSourced)) {
    # No script sourced, checking invocation through Rscript
    cmdArgs <- commandArgs(trailingOnly = FALSE)
    needle <- "--file="
    match <- grep(needle, cmdArgs)
    if (length(match) > 0) {
      return(normalizePath(sub(needle, "", cmdArgs[match]), winslash=.Platform$file.sep, mustWork=TRUE))
    }
  } else {
    # 'source'd via R console
    return(normalizePath(lastScriptSourced, winslash=.Platform$file.sep, mustWork=TRUE))
  }
})()

我已经将这个问题的答案打包并扩展为rprojroot中的新函数thisfile()。也适用于编织与针织。

    } else {
        ls_vars = ls(sys.frames()[[1]])
        if ("fileName" %in% ls_vars) {
            # Source'd via RStudio
            return(normalizePath(sys.frames()[[1]]$fileName))
        } else {
            if (!is.null(sys.frames()[[1]]$ofile)) {
            # Source'd via R console
            return(normalizePath(sys.frames()[[1]]$ofile))

                pth = rstudioapi::getActiveDocumentContext()$path
                if (pth!='') {
                    return(normalizePath(pth))
                } else {
                    # RStudio Console
                    tryCatch({
                            pth = rstudioapi::getSourceEditorContext()$path
                            pth = normalizePath(pth)
                        }, error = function(e) {
                            # normalizePath('') issues warning/error
                            pth = ''
                        }
                    )
                    return(pth)
                }
            }
        }
    }
}

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

请注意，getopt包提供了get_Rscript_filename函数，该函数使用与本文相同的解决方案，但已经在标准R模块中为您编写了该解决方案，因此您不必将“获取脚本路径”函数复制并粘贴到您编写的每个脚本中。
