session - maintaining an input / output log in R

Question

Is there an easy way to have R record all input and output from your R session to disk while you are working with R interactively?

In R.app on Mac OS X I can do a File->Save..., but it isn't much help in recovering the commands I had entered when R crashes.

I have tried using sink(...,split=T), but it doesn't seem to do exactly what I am looking for.

Many of us use ESS / Emacs for this very reason. Saving old sessions with extension '.Rt' even gives you mode-specific commands for re-running parts of your session.
