I think the original poster wanted to read data from stdin, not execute an entire script from stdin; this works on many UNIX-like systems:
d <- read.table("/dev/stdin", header=F);Otherwise, for code, you can simply pipe (or redirect) to R from the shell:
% R --vanilla --slave < input > outfile

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

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