It's possible to run R (or a c parent process) as a background process via a named pipe, and then write script files to the named pipe. However, the details depend on what shell you use.
The last time I tried (which was a long time ago), I created a small c program to run R, read from the named pipe from within c, then wrote it's contents to R's standard in. It might be possible to do it without the c program. Haven't checked.
