Subject: How to suppress the printing of warnings (Windows)?
I'm running R v2.0.0 on Windows 2000. The command options(warn=-1) did the trick. However, is there a way I may also stop these warnings from printing on my screen while using R interactively. I am working with the LOCFIT library.
I'm also planning to run my simulations in my department's Unix machine (R v1.9.0) in batch mode, would `option(warn=-1)' do the trick there as well?

options(warn=-1)
However, warnings and errors are sent to stderr not stdout except on
obselete versions (95/98/ME) of Windows, and so not redirected by that
sink() call. For me (Windows XP)
> sink("foo.out")
> warning("test")
Warning message:
test
as expected. So is this an obsolete version of Windows or a very old
version of R?
