Is there anyway I can write a script which feed input datasource from stdin and let R process it (maybe frequency report) then output the report to stdout? I can't seem to find much info on documentation or FAQ on this topic. Thanks!

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.

Thanks! That's what I was wanted to know.
Also, is there a similar way I can do read.table from a pipe?
For example, if there is a command that I am running to generate the
datasource, I want to read that data as it comes..
Thanks...

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
