Hi,
I am a newbie with R. My environment is linux and
I have a file. I call it barebone.R, which has one
line:
cat ('Hello World!\n')
I execute this file as:
R --no-save < barebone.R
And it does what I expect. What I get is 20+/- lines
of text, one of which is 'Hello World!'.
How would I go about getting rid of all but the line I
am after, 'Hello World!'?
Regards,
Tena Sakai

I had to browse 'man R' a bit before getting a hint. R --silent --nosave < barebone.R should do it!
