[R] options(errorfn=traceback)

Dear R experts---I may have asked this in the past, but I don't think
I figured out how to do this.  I would like to execute traceback()
automatically if my R program dies---every R programI ever invoke.  I
guessed that I could have wrapped my entire R code into


... oodles of R code

error = function(e) traceback(),
finally = cat("done")

but the traceback docs tell me that this does not generate a
traceback().  in a perfect world, I would stick this into my .Rprofile
and forget about it.  in an super-perfect world, it would be an
option() that I just don't know yet...
