Hi All,
Another newbie question. I want to write an R script that takes
argument from command line and runs and produces output to stdin.
You will find that difficult: did you mean stdout?
My mistake -- I meant stdout :).
For example if there is file foo.R with following in it.

args = commandArgs()
print(args)
then, when I run it like

it should print 'hello'

Use the all powerful here document feature of bash:
R --vanilla EOF # Pipe all subsequent lines into R.
### Here's my R code
require(tcltk)
tkmessageBox(message=It works)
## the end
EOF

Is it possible to do this sort of thing in R using something like this?:

Well, that isn't quite it because I tried it and it didn't work!
Mike,
I use a shell script to do this which also allows passing in command line
options.

Ah ha! This leads to the latest version of my little one-liner (called
doR):
#!/bin/sh
echo output - { $1 }; write.table(file=stdout(), .Last.value,
row.names=FALSE, col.names=FALSE); q() |
You can cheat by using the shell to write a small text file full of
commands, then source that file by using R CMD BATCH yourtempfile.R . You
can also write small text files with variables defined and values assigned,
and pull them in from your script.

What you really want to do might be solved by write.table(), e.g.
x - matrix(rnorm(25*2),c(25,2));
write.table(file=stdout(), x, row.names=FALSE, col.names=FALSE);
Thanks. That does what I want.
There is one remaining problem for my echo method.

I'm new to the list. I've used R and S-PLUS a bit for about 15 years but
am now working to make R my main program for all numerical and statistical
computing. I also use Octave for this kind of work and I recommend it (it
is also under the GPL). Here's my question: In Octave I can write
-BEGIN PGP SIGNED MESSAGE-

This has been done and I said I would integrate it into R.
It is on my list of things to do relatively soon. I have never
been entirely happy with the way arguments are handled and that is what
has put things on hold. And now that the R startup is a
