python - 如何设置 rpy2？

Question

嗨，我刚刚下载了 rpy2 和 Python 2.6。当我尝试运行在互联网上找到的一些示例代码时，出现此错误。谁能解释为什么会发生这种情况以及我该如何解决它？谢谢。

import rpy2.robjects as RO

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import rpy2.robjects as RO
  File "C:\Python26\lib\site-packages\rpy2\robjects\__init__.py", line 12, in <module>
    import rpy2.rinterface as rinterface
  File "C:\Python26\lib\site-packages\rpy2\rinterface\__init__.py", line 22, in <module>
    "This might be because R.exe is nowhere in your Path.")
RuntimeError: Unable to determine R version from the registery.Calling the command 'R RHOME' does not return anything.
This might be because R.exe is nowhere in your Path.

Answer 1

This might be because R.exe is nowhere in your Path

这听起来像是一个很大的线索。检查 Windows 环境中 %PATH% 的值。我希望它包含 R.EXE 的位置(可能类似于 C:\Programs\R\R-2.8.0\bin)。
