Thank you for your help. It answers my question but I'm still unclear about something.
I understand that

suppressWarnings() will suppress warnings
suppressMessanges() will suppress *messages*

What other *messages* type are there and how to suppress all of them. For example, I want to quietly *install* a package:

*> install.packages("pkgDepTools",repos="http://bioconductor.org",lib="~/.R/library-i686")
*

but I always get the following printed. How to suppress it ?

trying URL 'http://bioconductor.org/src/contrib/pkgDepTools_1.0.1.tar.gz' Content type 'application/x-gzip' length 145394 bytes opened URL

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?
