[R] Checking for a proper "stop" statement...

[Jonathan Greenberg]

Folks:

Consider the following two use cases:

goodfunction <- function()
{
stop("Something went wrong..."
}

# vs.

badfunction <- function()
{
notgood()
}

Is there a way for me to test if the functions make use of a stop()
statement WITHOUT modifying the stop() output (assume I can't mod the
function containing the stop() statement itself)?  For "goodfunction" the
answer is TRUE, for "badfunction" the answer is FALSE.  Both return an
error, but only one does it "safely".

I thought the answer might lie in a tryCatch statement but I'm having a
hard time figuring out how to do this test.
