python - Rpy2 Cannot Find R.dll -


i on windows 7 64bit python 2.7.9, have installed r-3.2.0 (also tried r-2.12.2 , r-3.1.3 got same result), added c:\program files\r\r-3.2.0\bin\i386 system path, added r_home system variable value c:\program files\r\r-3.2.0, added r_user value "matt", , installed rpy2-2.3.0dev .exe file, installed.

however, typing from rpy2 import robjects gives following error in rpy2\rinterface\__init__.py: 

traceback (most recent call last):   file "c:\python27\rpy2test.py", line 2, in <module>     rpy2 import robjects   file "c:\python27\lib\site-packages\rpy2\robjects\__init__.py", line 14, in <module>     import rpy2.rinterface rinterface   file "c:\python27\lib\site-packages\rpy2\rinterface\__init__.py", line 79, in <module>     raise runtimeerror("unable locate r.dll within %s" % r_home) runtimeerror: unable locate r.dll within c:program files\r\r-3.2.0

i have tried copying , pasting this: 

if os.path.exists(os.path.join(r_home, 'lib')):             ## added ##     os.environ['path'] += ';' + os.path.join(r_home, 'bin')    ## added ##     os.environ['path'] += ';' + os.path.join(r_home, 'modules')    ## added ##     os.environ['path'] += ';' + os.path.join(r_home, 'lib')    ## added ## else:                                   ## added ##     os.environ['path'] += ';' + os.path.join(r_home, 'bin', 'i386')     ## added ##     os.environ['path'] += ';' + os.path.join(r_home, 'modules', 'i386') ## added ##     os.environ['path'] += ';' + os.path.join(r_home, 'library')     ## added ##  # load r dll using explicit path # first try bin dir: rlib = os.path.join(r_home, 'bin', 'r.dll') # try bin/i386 subdirectory seen in r 2.12.0                ## added ## if not os.path.exists(rlib):                        ## added ##     rlib = os.path.join(r_home, 'bin', 'i386', 'r.dll')         ## added ##

into rinterface\__init__.py, did nothing.

i have tried copying bin\i386 folder bin folder, still makes no difference.

how rpy2 find r.dll?

last night made rpy2 install pdf addresses issue -- either r, pyhton, pywin32 or rpy2 linked in path not 32-bit.

maybe - rpy2pandas.pdf

(only thing have python in c:/python27/arcgis10.2/python.exe, otherwise else should port.)
