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.
Adel

use c() to make your condition a vector, try to use all() to return a logical value for the entire condition vector .
