R脚本从命令行 [英] R script from command line

问题描述

我想运行此示例脚本： http://mazamascience.com/WorkingWithData/?p= 912 从Windows命令行。所以我打开命令行并键入 Rscript tryCatch.R 1 。但是，我一直收到错误消息错误：R not found 。我设置PATH环境变量为 C：\Programme\R\R-3.0.1\bin 。如果我只输入 R.exe ，它会启动 R ，但它找不到要加载的包（例如未找到选项<defaultPackages>中的package'utils'）。我想我必须设置另一条路径到图书馆某处，但我不知道在哪里做这个。

I wanted to run this example script: http://mazamascience.com/WorkingWithData/?p=912 from Windows command line. So I opened the command line and typed Rscript tryCatch.R 1. However, I keep getting the error message Error: R not found. I did set the PATH environment variable as C:\Programme\R\R-3.0.1\bin. If I just type R.exe, it does start R, but it cannot find the packages that are to be loaded at start (e.g. package 'utils' in options<"defaultPackages"> was not found). I guess I have to set another path to the libraries somewhere, but I haven't got any idea where to do this.

更新：显式键入 PATH C：\Programme\R\R-3.0.1\bin （而不是仅仅将其添加到环境变量PATH的值），似乎 R 。但是，会出现一个新问题：在normalizePath< path.expand（path），winslash，mustWork> ;:path [2] =C：/Programme/R/R-3.0.1/library：访问被拒绝，与方法库相同。然后：调用：.First ...库 - > .getRequiredPackages2 - >库 - > normalizePath执行已停止。我使用的是Windows 7，我有管理员权限。

UPDATE: After explicitly typing PATH C:\Programme\R\R-3.0.1\bin (rather than just adding this to the value of the environment variable PATH) it seems that R is found. However, a new problem occurs: In normalizePath<path.expand(path), winslash, mustWork>: path[2] = "C:/Programme/R/R-3.0.1/library": Access denied, the same than for the methods library. Then: Calls: .First ... library -> .getRequiredPackages2 -> library -> normalizePath Execution stopped. I'm using Windows 7 and I do have administrator rights.

推荐答案

我发现它是一种特定语言问题，类似于此处所述： https：/ /stat.ethz.ch/pipermail/r-help/2011-May/276932.html

I've found out that it was a language-specific problem on Windows 7, similar to what is described here: https://stat.ethz.ch/pipermail/r-help/2011-May/276932.html

更改 PATH

After changing PATH to C:\Program Files\R\R-3.0.1\bin the script is properly executed from the command prompt.
