R help - Oct 2010 - sweave output

I'm just starting to use sweave with latex and have a beginner question
I expect this has been asked before - but  I cannot seem to find the answer

An input like:

<<echo=false>>X <- 1:3
X
@

Generates

[1] 1 2 3

Is there a way to suppress the [1] ?

I know I can write each term out using this

the line is \Sexpr{X[1]} \Sexpr{X[2]} \Sexpr{X[3]}

But there must be a simpler way.
Any suggestions?
If you send out an answer would you copy me directly as well as send it to the
mailing list


Thanks
Norm

This isn't really an Sweave question.  Sweave just prints what R would 
print.  To get R to print without the decorations, use cat(X, "\n") 
instead of
X (which is really a synonym for print(X)).  The "\n" says to go to a 
new line; it's optional in this example (because Sweave will insert a 
line break automatically), but it would make a difference if you were 
printing multiple things within the same code chunk.
