[R] Silently loading an R package.

[Yihui Xie]

please read the 'Details' section of ?require

     To suppress messages during the loading of packages use
     'suppressPackageStartupMessages': this will suppress all messages
     from R itself but not necessarily all those from package authors.

Regards,
Yihui
