The easiest way would probably be to do the hack of creating a temporary file to hold stdin, then call R to process that file. That would be easy to do in a shell script.

If this really won't suffice, this older message might lead to something useful:

--------------------------------------------------------------------------------

I've updated my scripting patches to R-1.8.0. These patches
allow you to write shell scripts in R (at least on *nix systems)
by putting

#!/path/to/R.bin --script

on the first line of the script file. If you're interested
in the patches, e-mail me at

Is there anyway I can write a script which feed input datasource from stdin

stdout?



I can't seem to find much info on documentation or FAQ on this topic.



Thanks!
