May I suggest to avoid cross-posting (without apparently reading answers) ?

Hello everyone,
I just joined the list. I am at my wits end trying to solve the
problem of installing Rpy2 on windows 7.
This is again a repetition of the same problem, but please bear with
me as nothing is working.
I am new to R and Rpy2. My problem is similar. I am using python 2.6,
R 2.15.1, rpy2 2.2.6, and Windows 7.
*R_HOME: C:\Program Files\R\R-2.15.1*
Typing "R" in the command prompt does not work.
*PATH: has these two--C:\Program Files\R\R-2.15.1\bin;C:\Program
Files\R\R-2.15.1*
*PYTHONPATH:
C:\Python26\ArcGIS10.0\Lib;C:\Python26\ArcGIS10.0\DLLs;C:\Python26\ArcGIS10.0\Lib\lib-tk*
When I run the setup.py I get "*error: no commands supplied*"!
I tried putting all files from bin/i386 to directly under bin.
In my rinterface/_init_.py this is what I did:
|# MSWindows-specific code
_win_ok = False
if sys.platform in _win_bindirs.keys():
import win32api
if os.path.exists(os.path.join(R_HOME, 'lib')): ## ADDED ##
os.environ['PATH'] += ';' + os.path.join(R_HOME, 'bin')
os.environ['PATH'] += ';' + os.path.join(R_HOME, 'modules')
os.environ['PATH'] += ';' + os.path.join(R_HOME, 'lib')
R_DLL_DIRS = ('bin', '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 ##
R_DLL_DIRS = ('bin', 'library')||## ADDED ##||
# Load the R dll using the explicit path
# Try dirs in R_DLL_DIRS
for r_dir in R_DLL_DIRS:
Rlib = os.path.join(R_HOME, r_dir, _win_bindirs[sys.platform], 'R.dll')
if not os.path.exists(Rlib):
continue
win32api.LoadLibrary(Rlib)
_win_ok = True
break
# Otherwise fail out!
if not _win_ok:
raise RuntimeError("Unable to locate R.dll within %s" % R_HOME)
# cleanup the namespace
del(os)
|
Nothing changes the setup.py error message. Please help!!
