[R] silent loading of packages

[Prof Brian Ripley]

It depends on the 'message'. In this case

> library(VGAM, warn.conflicts=FALSE)
> suppressMessages(library(VGAM))

both work.  (How did you manage to miss the first?)

In general, it depends on whether the 'message' is a message in the sense 
of message() or produced some other way.  sink() would work, but these are 
*messages*, so how did you use it?
