Hi,
I have a similar problem. After taking all the suggestions from Bitbucket on installing rpy2 under win7 with python 3.2. I installed RTools, defined RHOME, R_HOME, and R_USER and appended the path of R.dll. In the end, when running "python setup.py install", it it turned out to be following: File "F:\Program Files\Python32\lib\distutils\cmd.py", line 107, in ensure_finalized 
    self.finalize_options()
  File "setup.py", line 152, in finalize_options
    rversion = get_rversion(r_home)
  File "setup.py", line 191, in get_rversion
    rp = os.popen3('"'+r_exec+'" --version')[2]
AttributeError: 'module' object has no attribute 'popen3'
Can anyone help?? Much appreciated!


Combining difficulties, aren't you ? ;-)


Python 3.2 is not supported (Python 3.3 is), and MSWindows support is 
mostly DIY (some have reported to get it to work, fewer have 
contributed binaries).



Here the issue is deprecation of functions in Win. It will take a 
contributed patch to fix this. The Python documentation is giving a 
starter:

http://docs.python.org/3.3/library/subprocess.html#subprocess-replacements





I was bugfixing 2.3.0, and since at it I implemented the suggested 
changes to the default (dev) branch. That's completely untested; someone 
should try.

    Hi,

    I am struggling setting up RPy2 with Windows.

    My config: Win7 32 bit _without admin right_ (I understood they
    are not required, am I wrong?)
    - R 14.2 (C:\R\R-2.14.2\bin\i386\R.exe)
    - Portable Python 2.7 (C:\PortablePython\App\python.exe)
    - rpy2-2.3.0beta1.tar.gz

    I cannot modify environment keys from Windows GUI, but I can set
    them from command line ( for instance set
    PATH=%PATH%;C:\R\R-2.14.2\bin\i386), however it is not permanent.

    Using the link provided earlier on this mailing list
    https://bitbucket.org/lgautier/rpy2/issue/95/automagic-settings-for-windows 
,
    I tried to use both provided scripts with little success :

    The first one:
    *C:\Temp\rpy2-2.3.0beta1>c:\PortablePython\App\python.exe
    set_Rvars_win32.py*
    returned
    TypeError: _get_reg_vars() takes at least 2 arguments (1 given)
    Tring to look below the hood, this method is called from line 27:
        reg_vars = self._get_reg_vars()
    and defined from line 111:
        def _get_reg_vars(self, hive, key=R_KEY)
    The hove arguments seemed missing so I tried to pass MACHINE_HIVE
    and USER_HIVE with no success:
        TypeError: The object is not a PyHKEY object


    The second one:
    *C:\PortablePython\App\python.exe setup.py build --r-home
    C:\R\R-2.14.2\bin\i386 install*
    returns
    Traceback (most recent call last):

    '%s')." %'.'.join(rve
    rsion))
    TypeError: sequence item 0: expected string, int found

    It seems that the R versions does not get retrieved.

    Would you be kind enough to advise?
    Regards,
    Sam

        Thanks for the help, its great.
