Newbie R question PART2

Hi,

Many thanks to Wacek Kusnierczyk and Ted Harding.

I learned 3 new tricks.  (Not bad for a newbie?)

  $ R --silent --no-save < barebone.R
  $ R --quiet --no-save < barebone.R
  $ R --slave < barebone.R

With slight differences, they all do what I wanted.

Moving right along my tiny agenda...

Given the same one-liner,
  cat ('Hello World!\n')
would someone please show me how to turn this one liner
into a web page with Rpad?  

Obviously, What I want to build is a web page, where it
say "click <here>" and when it is clicked the screen
blanks out and give a line:
  Hello World!

I have looked at an example or two of Rpad, but it was
overly complicated for simpleminded newbie.

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!'?

An unusual request! I had to browse 'man R' a bit before getting
a hint.

  R --silent --nosave < barebone.R

should do it!
Ted.
