I'm trying to do realize the following:
I have 4 condtions.
If all conditions are satisfied I will paste("PASS")
If any of these is not satisfied I will paste("FAIL"). But I have to paste
the corresponding failure.

ifelse is a good solution but for a 2 conditions. Maybe switch or something
like this.

Does anyone have an idea how to do?

Thanks in advance.
