R脚本和命令行前端 [英] R scripting and command-line front-end

问题描述

我正在编写一个R脚本来在ubuntu的前端运行命令:

I am writing a R script to run the commands in the front-end in ubuntu:

Rscript my_scripts.R  my_file.txt output_file

但是，它给了我一个错误，例如错误:"Rscript my_scripts.R"中的意外符号

However, it gave me an error like "Error: unexpected symbol in "Rscript my_scripts.R"

我遇到了这篇文章 R命令行，将文件名传递给参数中的脚本(Windows).我引用答案"As I said in my comment, I would use Rscript instead of R CMD BATCH:"

I came upon this post R command line passing a filename to script in arguments (Windows). and I quote the answers "As I said in my comment, I would use Rscript instead of R CMD BATCH:"

所以我发现为了运行此程序，我必须安装

So I found that in order to run this, I have to install

sudo apt-get install littler

sudo apt-get install littler

根据此帖子在ubuntu上使用Rscript

当我完成安装此软件包时，它仍然显示相同的错误消息.有解决方案吗?

When I finished install this package, it still showed the same error message. Any solutions?

最好

推荐答案

您是否真的从UNIX shell提示符下运行了它?因为我可以通过在R提示符下键入该命令来得到类似该错误的信息:

Are you really running that from the unix shell prompt? Because I can get something like that error by typing that command at the R prompt:

$ R
  [startup noises]
> Rscript foo.r
Error: unexpected symbol in "Rscript foo.r"

否则，脚本中的内容也会被破坏.

Otherwise its something in your script that is similarly screwed up.

从Unix命令提示符运行时，一切正常:

When run from the Unix command prompt, all is well:

$ Rscript test.R
[1] 1.414214

其中test.R就是print(sqrt(2))
