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. On Sat, 18 Oct 2008, Tomislav Puđa wrote:

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 ?
