[R] Rscript: how to suppress all output

[johannes rara]

Thanks! I'm using Mac 10.6.2. This did it:

~/Documents > cat test.r
#! /usr/bin/Rscript --vanilla --default-packages=utils

suppressMessages(require(Hmisc))
suppressMessages(require(gsubfn))

a <- 1:100
print(a)
~/Documents > Rscript test.r > /dev/null
~/Documents >

-J
