hmm, does your usb have it's own python as well, or are you using your 
system python? If you don't have win32api, you'll probably need to 
install the PyWin extensions:

This might be an option, however, even if manageR did have this 
function, since you don't appear to have the win32 python extensions, it 
wouldn't matter in this case anyway... I'll see if I can add this in a 
future release.

I'm sorry I can't be of more help, but please let me know if the above 
helps at all? Also, see comments below:

change the above line to 'import os' without the quotes

same goes for the above line
> os.environ['R_HOME'] = "C:\Users\Darren\R\R-2.9.0\bin"
> parser = ConfigParser.ConfigParser()
> here = os.path.join( os.path.dirname( __file__ ),"config.ini" )
