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?

Dear all,
I'm a newbie in R. I am running simulations using a fixed bandwidth in
nonparametric regressions, sending all the output to a file myoutput.txt
using sink("myoutput.txt"), & R is printing all warnings by the end of
the simulation on the file. I know the source of the problem & can take
care of it. However, finding a 50 MB file (where all the output is
printed, e.g. myoutput.txt) by the end of the simulation exercise is not
quite pleasant. How could I turn them off completely?, so they are not
printed in myoutput.txt file.
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?
