[R] a rounding option for \Sexpr{}?

[Yihui Xie]

Hi all,

Currently Sweave does not format the (especially numeric) value in
\Sexpr{}, and I often have to round() the numbers explicitly,
otherwise I will get more than 10 digits, which is not necessary for
me in most cases. Is there a way to specify the number of digits to be
kept for values in \Sexpr{}? e.g. can we make \Sexpr{} respect
getOption('digits')?

Thanks!

Regards,
Yihui
