[R] Sweave encoding option

[Yihui Xie]

What happened might be that your vacation took too long. The encoding
argument was introduced in R 2.13.1 (July last year). Nothing has
changed in your Rnw document, but things have always been changing in
R, so the best thing to do is to check out help(Sweave).

Regards,
Yihui
