I apologize for being unclear in my original post. What I am trying to
achieve is to capture the stdin() connection and read in a single
keystroke - including arrow keys and the like - without having to have to
use the return key each time. My goal is to create a small UI for rapidly
looking through the results of a large simulation. As I think about it
more, though, it is probably going to be easier to dump the data into
files and look through it outside of R.
Thanks anyways,
Jon
