is it possible to throw a stop() that is so hard that it will escape
even tryCatch?
You can signal a condition that is not an error, and if tryCatch hasn't
been written to catch it, it will stop. For example,
g <- function() {
tryCatch(f(), error=function(e) NULL
cat("Still running\n")
}
f <- function() stop("Regular error") # This won't stop g()
g()
f <- function() stop(simpleCondition("I mean it!")) # This will
g()
Of course, you can catch simpleConditions too if you try.
