在Windows中通过终端运行R并保持R会话打开 [英] Running R via terminal in Windows and leaving R session open

问题描述

假设我有一个名为 test.R 的R脚本，存储在 C：\ 中，并且以下内容：

Suppose that I have a R script called test.R, stored at C:\, with the following content:

x <- "Hello Stackoverflowers"
print(x)

要通过终端运行它，可以简单地调用：

To run it via terminal one could simply call:

Rscript C:\test.R

如预期的那样，结果将是：

And as expected, the result will be:

但是，我想知道的是是否有一种方法可以通过Windows控制台运行 test.R ，但之后仍停留在已执行的R会话中，而不是关闭并返回控制台光标？也就是说，留在R会话中，而不是返回上图中的 C：\R\R-3.4.1\bin> 。

However, what I wonder is whether there is a way to run test.R via Windows console but after that staying within the executed R session instead of closing and going back to the console cursor? That is, staying inside the R session instead of going back, in the image above, to C:\R\R-3.4.1\bin>.

例如，当使用 python.exe 编译Python代码时，我可以通过传递 -i 参数调用 python.exe 。

For instance, when compiling Python code with python.exe I can easily accomplish a similar thing by passing the -i parameter to the python.execall.

如何

推荐答案

将此添加到您的.Rprofile：

Add this to your .Rprofile:

STARTUP_FILE <- Sys.getenv("STARTUP_FILE")
if (file.exsts(STARTUP_FILE)) source(STARTUP_FILE) 

，然后在R之外设置指示的环境变量，然后运行R。例如从Windows cmd行：

and then set the indicated environment variable outside of R and then run R. e.g. from the Windows cmd line:

set STARTUP_FILE=C:\test.R
R
... R session ...
q()

变化

有很多变化。例如，我们可以在特定目录（例如〜/ test）中复制.Rprofile文件，并将此代码添加到该副本中。

There are many variations of this. For example, we could make a copy of the .Rprofile file in a specific directory such as ~/test, say, and add this code to that copy

source("~/test/test.R")

在这种情况下如果R在该目录中启动，R只会运行test.R。

in which case R would only run test.R if R were started in that directory.
