如何从命令行运行R脚本文件 [英] How to run an R script file from the command line

问题描述

我知道有关此问题有很多问题，但是我已经尝试了所有方法，我想我只是不了解命令行在Windows中的工作方式。我有一个文件保存在桌面上的文件夹中，假设：

I know there are a lot of questions regarding this issue but I've tried everything and I think I just don't understand how the command line works in windows. I have a file saved in a folder on my desktop, let's say:

C:\Users\abika_000\Desktop\R models\myfile.R

这是我的R / bin或Rscript / bin：

Here is the directory to my R/bin or Rscript/bin:

C:\Program Files\R\R-3.1.0\bin

我想使用cmd提示符运行此代码。我将如何去做呢？

I want to run this code using the cmd prompt. How would I go about doing this?

我已经尝试过以下问题的解决方案，但是无论如何我都会不断出错：

I've tried this solution from the question below but I just keep getting errors no matter what I do:

从命令行运行R脚本

我输入的内容：

> R CMD BATCH C:\Users\abika_000\Desktop\R models\myfile.R
> Rscript C:\Users\abika_000\Desktop\R models\myfile.R

我得到的错误是：

'R' is not recognized as an internal or external command, operable program or batch file
'Rscript' is not recognized as an internal or external command, operable program or batch file

EDIT ::

向辉煌和Phil致谢。我通过输入以下内容来修复该问题：

Credit to splendour and Phil. I wound up fixing it by entering:

> "C:\Program Files\R\R-3.1.0\bin\"R CMD BATCH "C:\Users\abika_000\Desktop\R models\myfile.R"

我为这个可怜的问题表示歉意。我只是不确定如何在尝试使用R CMD BATCH或Rscript时使用cmd提示符/ directory

I apologize for the poor question. I just wasn't sure how to use the cmd prompt /directories in trying to use R CMD BATCH or Rscript

推荐答案

步骤1（如果尚未完成）是使用UNIX-y shell模拟器，例如 Cygwin 。
然后，假设它在Windows上可用（在Linux / OSX上可用），则可以使用包装程序 Rscript 。

I think step 1, if you haven't already done it, is to use a UNIX-y shell emulator, such as Cygwin. Then, assuming it's available on Windows (as it is on Linux/OSX), you can use the wrapper program Rscript.

或者，如果您有UNIX-y shell模拟器，则始终可以将输入直接通过管道传递到 R ，例如：

Or, if you have a UNIX-y shell emulator, you can always pipe input straight into R, e.g.:

R --no-save --no-restore < your_script.R
