导入rpy会出错

Question

我尝试使用http://sourceforge.net/projects/rpy/files/latest/download?source=directory

上的下载来安装rpy

我收到此错误：

from rpy import *
Unable to determine R version from the registry. Trying another method.

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    from rpy import *
  File "C:\Python27\lib\site-packages\rpy.py", line 53, in <module>
    RHOME = rpy_tools.get_R_HOME()
  File "C:\Python27\lib\site-packages\rpy_tools.py", line 57, in get_R_HOME
    raise RuntimeError("Couldn't execute the R interpreter.\n"
RuntimeError: Couldn't execute the R interpreter.
Check whether R is in the execution path.

为什么要这样做？我怎么能阻止它？

Answer 1

在安装R期间，会显示一个复选框，为您提供将R版本号添加到注册表的选项。

也许你没有检查过？重新安装R可能会有所帮助。
