Hi all,

I am having some problems calling a python script from R that resides
in a folder that is in the path (WindowsXP):

> system("quickPadTool.py")
Warning message:
In system("quickPadTool.py") : quickPadTool.py not found

# I also tried 'shell' (and shell.exec as well).
> shell("quickPadTool.py")
'quickPadTool.py' is not recognized as an internal or external command,
operable program or batch file.
Warning message:
In shell("quickPadTool.py") :
  'quickPadTool.py' execution failed with error code 1

I can run the script fine from a command window just fine, from the
same directory.

Any pointers?
