[R] read input from STDIN

[yiping.fan@syngenta.com]

Hello,
   I have a perl program which produces the input. Instead of print it to a
file then let R read the file,
I want to let R to read the input directly from the perl output, 

I am using  a PERL IPC::open2 module for this, 

local (*Read,*Writer);
$pid = open2(\*Read, \*Writer, "R --no-save --slave< my.R")

#input to R
for(){
  print Writer data;
}
close Writer;

#R output
@result = <Read>;


How can "my.R"  read the stdin and figure out the relationship in the data?
I tried realLines(), does not work.  Thank you very much for your help!!
