Thanks for all the suggestions, everyone! I should mention the application: A debugging tool for R (written in Python). R's internal debugging facilities are primitive, limited and clunky, a lack that my program is intended to remedy. For example, R's own debugger doesn't have conditional breakpoints, but my program adds them.
My program writes commands to the R session, as if the user had typed the commands him/herself. As I said, I add a lot more commands, by handling them within my program. The current version is at http://heather.cs.ucdavis.edu/debugR.html It's basically for Unix-family machines only, because it relies on "screen." I've gotten requests to port it to Windows, hence my query to vox-tech. I think the simplest solution may be to use Python to open a pipe to R, and then have Python accept input from either the keyboard or the debugger, say using select().
