I think the `trick' is how text for parsing is sent to R, and the answer 
is via the command line, using C redirection (and ptys under Unix).
I've already suggested that approach a week ago.

This thread is getting very bitty, and I am still waiting for a clear 
statement of what it is that Jim is trying to achieve.  It sounds as if 
using redirection (and the -ess flag under Windows) is what is required.
