Hi R-People:
I use 2 machines: a machine with a Windows XP operating system, and
another with a Linux Ubuntu OS. I transport my code between these 2
machines. However, pathnames to data files always need to be "adjusted"
to account for the OS that I'm working on.
Here is my question:
How do I write code to detect whether I'm using the XP or the Linux
machine?
If I knew this, I could write my code in a way so that I didn't have to
adjust path names to data file all the time.
I checked the archives... didn't find anything, but perhaps didn't know
the right search terms...
Thanks for your help, R-community! Please respond to:

See ?.Platform
For example:
> .Platform$OS
[1] "unix"
It's always dangerous to say always, but "in general", the use of:
Path/To/File
with *forward* slashes, will work on both Windows and Linux, including
the use of relative paths.

and

for some hints.
