[R] cross-platform code: windows or gnu/linux?

[Russell Senior]

I am writing some R code that generates some figures.  I am primarily
developing on GNU/Linux, but will ultimately run the code on Windows
in order to get WMF files I can integrate in an existing document.
The win.metafile() function, of course, doesn't exist in the GNU/Linux
version of R.  I am contemplating writing an abstraction layer that
runs the right thing, but I need to know how the code can figure out
which platform it is running on.  I searched the mailing list archives
and online docs but didn't find anything relevant.  Pointers?  Thanks
in advance.
