Hi Bert,
Thanks for the reply.
The use case I presented involves working code, not diagnosing a script
in development.
The concern is running a script where something changes outside of the
script, as I stated. An example of a change is a data source changing
perhaps the columns in the data source, or even changing the spelling of
a column. The point is something changes.
The question then becomes how to be aware of the change when the reset
of the script runs fine, as I presented.
Think of having a script running daily where you are not running it
manually. How do you know there are errors in the script processing at
this point?
Does this question now make more sense?

Hi,
I am thinking about awareness of errors when an R script runs.
My concern is I have an error-free script. I run it for months on end
without problems. Then, something changes somewhere causing an error. My
wonderment is how R will tell me I had an error in the script, but the
rest of the script ran without impairment.
QUESTIONS
What are some of the more helpful options available to an R developer to
capture errors in a script run?
What are some of the best processes to implement these more helpful options?
Thanks,
