Dear R experts---I think I need to figure out how to stop in my error
function without triggering an error again.  so, I think I need the
equivalent of C's exit(0) call.  Here is what I mean:


and die.R is

# in my .Rprofile, but for now in die.R
options(error=function(e) print(traceback(sapply(sys.calls(), deparse))) )

f <- function()  stop("I want do stop here")
stop("pgm should have stopped by now in my main code\n")
cat("still not stopped?  yikes!\n")

advice appreciated.
