R help - Nov 2009 - 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.

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.
