This is a python not an R problem.
Use of redirection is handled by a shell, not by the executable (usually:
it could depend on the compiler). The Windows system and popen commands
(and hence R's system()) does not use a shell: POSIX OSes do.
It will be cleaner to use Rscript to run scripts.
Please ask Python questions on a Python help list.

Hi,
I'm trying to execute R-script from Python. I'm using R 2.7.2, Python 2.5
and WinXP.
I don't won't to use Python/R interface because of nature of project.
You'll need to explain the arbtirary restrictions you are imposing here.
Python code :
import subprocess
command = 'c:\\Program Files\\R\\R-2.7.2\\bin\\Rterm.exe --vanilla -q
<d:\\test\\run\\geneBank.r> d:\\output.out'
subprocess.Popen(command).wait()
After that, I get error messages on Rterm.exe terminal :
ARGUMENT 'd<:\lloydMax.r>' __ignored__
ARGUMENT 'd:\output.txt' __ignored__
Why ?
