There are scripting front-ends to R for these tasks. A few years ago Jeff and
I released 'r' (aka littler), R Core followed up with Rscript a few months
later. I still use r more.
In r / littler, all calls to library() are wrapped in suppressMessages()
because I too hate that echo from library loads. So here is what you could do:
e...@max:~$ r --package=fortunes --eval="print(fortune())"
Ah, so that's why my report of a bug in the RCheapViagra package didn't get
through....

I use R. My company benefits from it. My clients benefit from it.
...and I sleep just fine (when I do sleep)... :-)

Soon, they'll be speaking R on the subway.

Doing the same with Rscript is left as an exercise....
