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

Subject: Re: [R] silent loading of packages
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?
