Hello,
Does anyone know if it is possible to find out whether a calling function
exited with an error or not inside of an on.exit() call? I'd like to use the
same error cleanup function inside of several functions, and for aesthetic
reasons would prefer not to surround the body of all of these function with a
tryCatch.
Something like this:
isError <- function() {
parentError <- ???
if (!parentError) cat("No errors here!\n")
}
X <- function() {
on.exit(isError())
1+1
}
> X()
[1] 2
No errors here!
Thanks,
Robert
