Silently loading an R package.

Hello.

I've been working an a binding between OCaml and R (i.e. calling R from
OCaml, mostly). See below for a taste of it.

I'm currently wondering how to load a given R package silently. I tried

? ? ? ?require(xts, quietly = TRUE)

but I still get some ugly output. Is it possible to squeeze off this output
on stdout?

All the best,

Guillaume Yziquel.

Le chargement a n?cessit? le package : xts

Attachement du package : 'zoo'

xts now requires a valid TZ variable to be set
?no TZ var is set, setting to TZ=GMT
- : R.sexp = <abstr>

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.
