R help - Aug 2009 - globally set digits=3 in Sweave

Dear all
I would like to globally set
options(digits = 4)

in an Sweave document. I've read this thread [1] where it was
suggested to set the above option and pass every printed number
through format(). Aanother way to do so would be to round(expr, 4).
However I would like to set the digits option once per document so
that every number printed respects it, without the need to pass every
time through a formatting/rounding function. Is this possible in
Sweave?

Thank you
Liviu

Why not put

<<echo=FALSE>>options(digits=4)
@

somewhere near the top of your document?
