[R] 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.
