[R] R command line usage

[Deepak Chandran]

Hello,
   
    Usually if I want to run R code from another program, I generate an 
R script and run R BATCH. However, I have been wanting to access R's 
command line from another program. In other words, I want the std output 
from another program to feed into R (command line). Is there any way to 
do that? I would also like to collect R's response using std input.

Thanks
