[R] question about using a remote system

[Greg Snow]

Will R be able to send one batch of commands to the remote machine, then wait for the output?  Or will there be back and forth with new commands based on the output from the first commands?

You may want to look at the nws package for one way to have jobs run on a remote machine.
