在R包中添加对（Python）命令行程序的调用的最佳方法？ [英] Best way to add a call to a (Python) command line program in an R package?

问题描述

我制作了一个R包，其中包括，调用python命令行程序与以下代码：

I made an R package that, among other things, calls a python command line program with the following code:

py_loc = paste('C:/Python33/python.exe',system.file('exec', 'example.py', package='examplePackage'))
command <- paste(py_loc,"-e example")

它运行程序 example.py 示例包含Python可执行文件的 exec 文件夹 C：/ Python33 /python.exe 。因为我使用Windows，并且我想与其他Windows用户（但非Windows用户）共享它，我不能使用rPython来编写代码。
问题是 python.exe 将位于其他用户不同的地方。

It runs the program example.py in the exec folder of my example package with the Python executable C:/Python33/python.exe. Because I use Windows, and I want to share it with other Windows users (but also non-Windows users) I can't use rPython to write the code. The problem is that the python.exe will be located somewhere different for other users.

我的想法是添加一个 config 文件，您可以在其中设置Python可执行文件的位置，它作为函数的输入。是否有更好的方法来添加对R包中的（Python）命令行程序的调用？

My idea was to add a config file where you can set the location of the Python executable, or to ask it as the input of the function. Is there a better way to add a call to a (Python) command line program in an R package?

推荐答案

不能在Windows上工作。
然而，rPython的作者为Windows编写了一个版本：
https://github.com/cjgb/rPython-win
rPython和rPython-win都需要先安装Python，然后将R包指向。
我最近学到了另一个包装包，PythonInR： https://bitbucket.org/Floooo/ pythoninr /
我没有尝试过，但文档看起来很大。

"rPython does not work on Windows yet. " However the author of rPython wrote a version for Windows: https://github.com/cjgb/rPython-win Both rPython and rPython-win require that you install Python first, then "point" the R package to it. I recently learned of another 'wrapper' package, PythonInR: https://bitbucket.org/Floooo/pythoninr/ I have not tried it out but the documentation looks substantial.
